Supports or rafts

This part does not need supports or rafts.


Use of one perimeter line. When the designs are complicated, the use of one perimeter line is recommended because more than one could leave holes in the part.

Layer Height

High layer height, i.e. 0.25 mm for a 3D printer with 0.4 mm nozzle, since it does not affect any detail of the part.

Printing speed

Medium printing speed, but low printing gap speed.
