Professional Poker Chips

Ever since I taught my children to play poker, we love to spend evenings playing
The next step to the candy was the generic chips, just colored plastic pieces and I was asked to try making them with the 3D printer.
I looked at many projects found online but none satisfied me, so I decided to make them by redesigning the form from scratch
It had to have the following characteristics:
1. Being modular, that is, allowing you to always use the same parts to create different values
2. To be totally customizable in colors and writings
3. To be easy to assemble and possibly without the use of glue
4. To be as similar as possible to real casinos, in size and weight
5. To be printable in different parts with colors because I have a printer with only one nozzle and it only prints one color at a time
In particular:
1. Be modular: I created the different parts of the chip so as to print as few different pieces as possible. The complete chip consists of 5 different parts of which 4 are 3D printable The value of the chip fits into the half chip and then everything fits again in the crown and the same is done on the opposite side.
2. all the single pieces can be printed in different colors, even the background and the font of the chip value can be customized as long as certain conditions are respected (eg the font must be able to be printable without separate parts, I used the font " Stencil ")
3. For the editing I used a feature that is not normally appreciated in FDM prints, that is the signs of the various layers. I did a lot of tests to be able to get the right joints so that they hold up without the need for glue even if it is possible to put a drop of glue on the ends of the two half chips to make them hold better
4. The chips have the same dimensions as those of the casinos and as regards the weight I have foreseen the insertion, when assembling, of an iron washer to obtain the necessary weight. The authentic ones have a weight that can vary between 8 and 10.50 g each. With the iron washer these weigh about 9.2 grams.
5. Being able to print with only one color at a time meant that the chip was made up of many parts each with only one color.
