It's just a modification of rpgweb's excellent model. The changes are as follows:
- snap joint replaced by friction joint
- added fillets
- change the position of the slots on the modifiers
- slot walls have been reinforced and prolonged
- reversed the click mechanism to make it easier to substract the hp
I printed in PLA with a layer height of 0.2 with no problems at all.
There is a .step file for top piece, so you can adjust tolerances to fit your printer.
The author remixed this model.
