i have printed the STL parts but unfortunately it is absolutely not possible to fit the parts "Turntable_Base_large_version_35cm.stl" and "Rotary_Arm_-_2x.stl" together.
At first i thought it could be slicer setting ... but it's not.
Based on the design from the large version it's simply impossibe to fit them together. See screenshot below. The normal version (Turntable_Base_smallNema.STL) is designed correctly with 10,00mm thickness and should match.
This should be changed to avoid other people having this problem as well.
Beside this i personally would prefer to have more screw connections instead of perfect fit desgin which are always difficult because of different slicer settings. Maybe this could be an idea for next evolution. ;-)
