Great stuff. I am used to miss good contributions because i almost only hang around in WO all the time.
Solidworks seems to be a great piece of software. As i do more simple stuff (at smaller scales) i still go the CAD ->CAM route using a more simple program for milling.

For mechanical parts it is one of the best software, it is easy to use and the CAM (SOLIDCAM) is integrated, so it makes it much easier if you need to make any adjustments to the drawing

Yes, i have to go back and forth between CAD and CAM. The worst is that if i need to update the DWG, i have to define all the cutters/depths/speeds from scratch again. It's not a problem with drawings consisting of a few curves, but still... annoying.

I've been looking at some of your pieces, all great and very beautiful too, what's your manufacturing process like?

Thank you for the kind words. My process probably isn’t as cool as yours and I’m sure the machine is not as expensive, but it does the job pretty well. Just some good old fashioned metal on metal engraving. I have a clip I uploaded to X (twitter) of the process that I’ll link below. Feel free to hit that follow button. LOL

That is pretty awesome.  Has a bit of WoodCollector vibes to it, but I'm jealous.  I would recommend if you want to give it some color not to paint it, but powder coat it considering the material, but it looks great as is too.  Surely people are going to be asking you to make them one too as it's a great display piece.  Might even be good to throw it in some sort of frame and display it on the wall or as a paper weight on your desk.  If you do another one grab some video of the process as well.  Would probably make for a good YouTube video.

Yes, I think I'll leave it as it is, at most a polishing paste to give it more shine, specific aluminum was used for molds, so the finish is top quality.

I was thinking about making something to put on YouTube, but the problem is that this type of piece took 8 hours to complete (each side, total 16 hours), we didn't have a machine available during the day, so I left it running during the dawn, I left at 6:00 pm and when I returned at 7:00 am, all the machining of the bitcoin had already been completed. I only managed to take a few photos while I was preparing everything.

In the past, we had a camera installed inside the machining center that broadcast live 24 hours a day... it was really cool to watch the parts being manufactured from anywhere in the city

Do either one of y'all know how turn a design into a bas relief by simply uploading to some sort program like the lithopane (3Drocks) one?
I have designs but no intention on making the bas/STL anytime soon unless there's something easy out there.

I don't know this lithophane, I looked it up and found it very interesting.

Is it capable of doing this (embossed images) with any image? You can create a lot of cool things with it.

ahh yes I could have sent you a file as well - but you did an excellent job! the font is called Dodger - but do not write anything on the back - leave it smooth.

is it possible to have the writing around the edge (just inside that lip) about the forums and with my forum name? (Just none of the MJM text)

and then what would something like this cost?

If I understand correctly, is this how you want it?

not sure what you mean by exterior design - I would not want the MJM logo used at all

it's more of a curious question to see if other designs are possible

With your logo I imagined something like this and created a model. The result is basically this, I would just like to know what font you used to write, as I couldn't find it here to put the name on the back of the 3D model

would you make other similar coins? maybe even of other coin designs?

Yes, I could do another type. I would need time and know exactly what it would be.

About this bitcoin I could make a change to the 3D model I made and add your name, if you want to make a physical piece too. As a courtesy, free.

I was just thinking any other coin - the one in this picture is the most used design.

like a cas coin or a delos coin - or even what about with my logo?

You would use the exterior design of these coins but replace the central logo with yours, is that it?

This is nice and attractive, you must have spent a lot of time designing something unique like this. Hope it didn’t cost you plenty money to make one or it is your handwork to make crafts using metals like this? It is good to see innovative things to make bitcoin more popular and known. You’ve done well, the polishing was top notch and I commend your efforts in this.

I work with CNC, and I exchanged the execution of this bitcoin for myself in exchange for making other parts for the company's owners, it ended up that it only cost me my time. We make agricultural parts here and I've been wanting to do something related to bitcoin for some time, luckily a machine was idle and I managed to do it over a weekend. Thanks for the comment, I'm glad you liked the work as much as I did.

to change the size, just use the scale tool in solidworks

Very cool idea but unfortunately the use of that coin design kills it IMO.  

That coin is the quintessential no coiner coin!

It's really big, but I'll explain why

the writing tool I used, its diameter is 6mm with an angle of 60 degrees and a tip radius of 0.2mm, in other words it is not big but it is not small either, as Bitcoin is extremely detailed it would not reach certain places because the entire path is based on the solid (3D model) so it respects the entire surface... To solve this we would have to place an even smaller tool, and with a smaller tool, we must necessarily reduce the cutting increments and machining feeds. which would result in much more machine time, which I didn't have available on the day. I needed the piece to be manufactured overnight. Where the equipment would have free time.

So the size that was an interesting value for money was this, diameter 130mm. the original idea was not a coin or something, it was an item to display on a table or shelf

Given that the 3d model is quite complicated, I wonder, did you design the model yourself, or had someone else do it?

The cost of one of these is per machine hour, it costs about 50 dollars per hour, the piece in total took about 7 to 8 hours. It really is a unique and very exclusive item.

That makes sense. Sheet metal is not cheap, and it's usually machined in rectangles (from my experience) - but since this is truly a 3D item, I guess you needed to look hard for a place that deals with large blocks of aluminum. By the way - what are they doing when they are not manufacturing exotics like this?

the model is a coin design that is widely used. MJM did this design and many have used it. this one has some changes though with adding of the forum and forum account name and the difference of text in the box on the back.

I have used the same design to 3d print similar looking rounds.

WOW thats some piece, its kind of in the same league of giant collectibles as The Bitcoin Penny's
man hole cover !

This would look even better polished IMO. Polished Aluminium turns our really well!

Polished aluminum has a chrome appearance, an incredible look.

As the piece has a lot of details, the polishing will be complex, I'm going to try to do the same, because I'm afraid of someone damaging it.

Exactly, the modeling he created is perfect.

That is one heck of a coin for sure!  That would look great hanging on anyones wall!

 Great job...and also goodluck with your sale if you ever do sell.


It was really beautiful and with an excellent finish. I don't think about selling this one... maybe if they pay 1 Bitcoin for it I can think about it lol  Grin Grin... thanks for commenting

Woahh great this is a very cool collectible item buddy! Seeing clearly the physical bitcoin is quite detailed and of course this is very exclusive, the decoration in your room will be quite interesting.

To be honest I want to have a better collectible, if I buy from outside then I am heavy from the shipping costs that are so high, while I see there are online stores that I often visit but the quality is really not worth it, but it is a cheap price.

The cost of one of these is per machine hour, it costs about 50 dollars per hour, the piece in total took about 7 to 8 hours. It really is a unique and very exclusive item.
$50/hour? That means with the physical Bitcoin creation, say 8 hours * $50 means you have spent $400 for this creation.
Is this too expensive or cheap in your opinion?

To complement, it was this time for each side, total 2 sides, 16 hours.

An alternative would be 3D printing in resin. The price drops a lot

the complete manufacturing we have a total of 800 dollars on average, as I work on it, I did it myself, the cost was just my time. Due to the quality and exclusivity, I don't think it's expensive, but it's relative, it can be expensive for one person and not for another.

A 140mm cylinder was used to manufacture. We manufacture cold box molds for foundries and also parts for agricultural machinery.


Looks very cool @OP!

Now you can create your own steel plate to hold your seed phrase instead of buy it from someone (of course don't write the 12-24 words into the 3 models lol).



I'm thinking about doing this, and engraving the seeds with a laser

Awesome work here!  Very cool piece.

You might want to consider moving this post to the collectibles section - https://bitcointalk.org/index.php?board=217.0

That board/this site is where the "birth" of the physical bitcoin came to be.  I did a quite little historical timeline write up for example- https://bitcointalksearch.org/topic/historical-timeline-of-the-physical-bitcoin-cryptocurrency-collectibles-5174217

Either way, you should post about this on the collectibles board, everyone there would really appreciate it!

Very unique interest you have. What was the total cost in developing one coin ? If the final result can be improved further , you can take input from other members here and may be start a separate thread for selling these as collectibles. I would personally love to own a coin like this. Only problem is that bitcoin legal condition is yet not clear in my country and I am afraid that holding such a coin or promoting crypto here physically might land me in some legal trouble one day.

They look heavy, but the pictures of the final result make them smaller in size and dimensions.
I liked the idea. The final design is good, although it can be developed, but I think you liked the idea and I am happy that you made your own final product.

Create a low cost design service if you have access to ROMI D800 machining center at a low price.


Dimensions 130mm x 20mm, weight 750g, so you can make it any size you want by scaling the project

Hello everyone, for a long time I wanted a physical bitcoin to put in my room, like a decoration, I even bought some online but I never liked their quality and I always found them very ugly, as most are made in low-quality matrices. quality. So from that I decided to make my own bitcoin made on a CNC machining center, I really liked the result, it was a unique and VERY EXCLUSIVE item, detail, I wrote the name of our forum and my nickname.

I hope you like it as much as I did, it's the way it came out of the machine, I still don't know if I'm going to have it painted or polished to make this item more beautiful.

I will post photos of the final result and below photos of the manufacturing and development. It's even cool for those who have no idea how metals are transformed to know it too!


edit: NEW PICS!










detail for my nickname and forum name





development and manufacturing carried out with SolidWorks and SolidCAM software





Now in the manufacturing process, the part was made in a ROMI D800 machining center
