Geeetech i3 Hotbed adjustment nut

First thing printed !! The wingnuts to adjust the hotbed are not very confortable to turn, it is a two hands job, so the first thing I printed are these knobs. As I had only some nylon to print with, I added a .5mm skirt to make the piece stick better to the bed as in the first try it got loose and went moving around. I printed without supports, and when the print was high enough, I paused and drop the M3 nuts in, so the top side would have something to lay on. Don't put the nuts too soon or the extruder will catch on them.

You can make this in different sizes with this customizable heatbed knob customizer...
