Hey there,
the tweezers holder can hold up 1 tweezers but i uploaded also an version for 2 on my profile. It sits tightly on the skadis so that it does not wobble.
Layer height: 0.2
Loop walls: 2
Infill: 25% Crosshatch
Support: Tree (auto)
Recommended material: ABS for max. stability, but PLA/PETG will also work
I recommend an 5mm brim
Have fun with printing :)
