Here is a Crystal Frog I made using TinkerCAD, Fusion 360, and a banjo frog model from Tcad user Geometricity. The crystals were randomly generated using math and a program in openSCAD.

edit: on v3 and the original lower the model in cura by -2.0mm for best first layer prints. v4 is lowered in Tcad (thus innacurate) but is lowered by -0.9mm(Tcad mm) so should transfer to cura fine.

Print at whatever size you wish i used 280%

EDIT: this model needs to be lowered in the slicer approximately +- 0.2mm to get good bed adhesion. V4 is the best version of the model and should need even less adjustment.

Please post your makes if any would love to see this model created by others. Also thanks for the incredible support, this is my first public model.
