This drawer can be mounted under an IKEA Lack table as used for the famous enclosure. It consists of two cheap IKEA Kuggis boxes and the three printed holders.
The boxes used are 13x18x8cm and 18x26x8cm:

The shown holders are printed using a 0.4mm nozzle and 0.3mm layer height. No Support is needed.
I added some 5.1 mm holes for inserts at the back, which I might use in the future to add some end-stops for the drawers.
The author marked this model as their own original creation.
