ok update - let me preface with the acrylic used is scrap pieces - production acrylic will be new and still have the protective covering over the acrylic for the recipient to remove. So, please try and ignore the scratches all over these acrylic pieces.
the screws do hold the pieces together well - these are 4mm holes on the back side - when the production acrylic comes in, we will go with a 3.5mm hole - did try a 3mm hole but it cracked the acrylic so we stepped up to 4mm - do not have any more sheets to try another set.
Here are pics of both a single and a double holder.
first pic is just the cards inside the center insert -which can be a variety of colors - I would need to know what color you want in advance though.
pics from the front.
pics from the rear.
I am also sourcing some better looking screws. Changing the screws will not affect the price.
My initial idea is $12-$14 for the double and $9-$10 for the single.
Did try some magnets but my concern is that somehow the two halves come apart/slide apart and the cards fall out or get lost. They are also more expensive than the screws and would require more work to install.
The first batch will be for 24 doubles. More acrylic will come later and can make more doubles (I think yogg said there was less than 200 of the doubles being made) I would love to be able to supply each recipient of a double with a holder if they want!
Also with more interest - if that happens we can look to make singles and once the larger laser is in place can look at doing larger holders as well.
Open to opinions, input, suggestions etc.
