My colleague's trash can base broke (probably from IKEA). Since 3D printing is ideal for repairing such damages, I made a model. 

Original, broken is black, 3D printed is white

Everything works great, the model is stronger than the original, it holds its place perfectly.

It is modified so that it can be printed without supports, Enjoy!

Printed from PLA, 0.2 layer, no supports.
