Ikea Moppe Drawer Holder

Had some drawers leftover from the IKEA Moppe bookcase project for our sons room, based on this IKEA hack. Decided to re-use them. In my small workshop i have a shelf where I can mount them underneath, therefore I needed a holder. The hole fits a 3,5 mm countersunk woodscrew.

Designed in Tinkercad, I tried to make a design which is fast printable without support and also material efficient. 

Print settings:
Resolution: 0.2 mm
Nozzle 0.4 mm
Supports: depending on orientation (see below)
Material: PLA+

Additional instructions:
The both side panels were printed flat, the center part is printed upright (see below). For the center part a large brim was used because of poor adhesion resulting in a failed print.
