Huge drawer :
- 230 x 289.5 x 31.5 mm internal dimensions in the drawer
- 250 x 300 x 38.5 mm full external dimensions base included

Printing on Qidi Xmax 3 in PLA. ASA/ABS or something else with rigid properties should be good. I don't recommand PETG, I think it's to flex for the base.

4 walls / 5 top / 5 bottom / 40% gyroid for the base
3 walls / 5 top / 5 bottom/ 25% gyroid for the drawer
No support

Option : I put paraffin on the base to protect it and for perfect slide.
