I modeled the claw in Zbrush and printed with Prusa MK3S and Prusa white PETG @ .2mm layer height. There is three models available with a slot sized for use in the UK with a ten pence coin and one for the US quarter and one for a one Euro coin(sizes based on google search). i have also included the 3MF project files I have also made the model available in STL format. Supports required and blocker enforced support required for coin slot when printing.
