I made these simple drawer knobs/pulls to replace the ugly ones we had in our cabinet before. They are designed to be easy to print without supports.

There are two versions, one has an M4 nut embedded in mid-print. The other has an M4x6 heat-set insert (also mid-print for extra strength). Just slice the part and add a pause to the level just after the nut/insert opening. Adding a dab of glue on the nut helps next layer to adhere better, but is not required, the print will work out anyways.
