I I printed it with Pla+, but you can use another type.
a support for the bed is necessary.

i have used 100% infill ( only 8g filament).

For the assembly you need:
one M2x 6 or 8 and one M2 nut.
two M3 x8 and two M3 t-nut 2020 I have not uploaded the model to print because I think it is already much on printables. but if someone needs just leave a comment and I will upload a t-nut M3 stl.
