Sharps Box

This is a sharps box that I designed! It requires zero supports and should work with any print settings. Do keep in mind the warping of the corners, potentially better with a raft. 
 

FIX FOR WARPING
To print without a raft: In PrusaSlicer, I added small circles (8-10mm diameter) around each corner with a height of the current layer height and merged them with the box. These can easily be cut off once printed.
