Download the file and adapt the parameters
The opener is designed around a 10 Swiss cent piece.
Change the parameters to fit the dimensions of your coin. Important to do this very carefully. If dimensions not correct the mould can leak, as it will not close properly and a little gap will remain (if the coin is too wide), or plastic will flow on the coin, covering it (if the coin is too thin).
Adapt the parameters necessary for CNC milling.

CNC milling
Adapt the parameters to fit the CNC milling process. Please seek for advice to someone in your community that has experience, or order the mould from a Precious Plastic Workshop through the Bazar.
Material: aluminium/steel

Feedback from our experience
Material of mould: aluminium. We have been using the mould for 5 years, it has scratches now, but overall works very well. With steel you should have a longer lasting mould.
Plastic used: Polypropylene (works perfectly)
Colors: nice to have a color mix. Works great with transparent. People love black/white mix.
Injection: quite easy as the mould is not too thin on any part. Mould rarely requires heating due to compact shape and no thin parts. Important to press enough as otherwise in the bottom the plastic will not adhere nicely to the mould, leaving an unfinished touch"
