68x82mm stamp handle (for bigger stamps with the same handle)

if you want to add a logo or something, you can use any CAD program. the easiest is probably TinkerCAD but if you have any local CAD programs (Fusion360, AutoCAD, SolidWorks, Rhinoceros3D) those will probably give you a better result.

I myself used a logo of 3mm height because the base is 7mm thick. this way I can print the model sunk down into the buildplate on Cura (see second picture) to print the handle, and for the TPU part I do the exact same thing but the other way around (see third picture).

re-modelled the entire thing basically
