Hex Nut Screw Knob

This simple print can replace a missing/broken plastic part that is commonly found on different products that include clamps and similar things. In my case, we had bought a Christmas tree, but it turned into a huge dilemma when our tree stand couldn't support it because one of the clamps had nothing to drive it in and stay in place. The device slides onto the nut and flexes around it to secure itself. For reference, the hex nut was about 3/8 of an inch tall and half an inch wide.

Supplies

CAD software - I used Fusion 360

Slicing software - I used BambuStudio

Any 3D printer

Filament of choice, but preferable PETG for strength and slight flex

Extrude it in 2 inches

Step 16: Sketch #8

Keep following these sketches and dimentions

Step 17: Extrusion #8

Extrude it in 0.05 inches, and you are done with the design!

Step 18:

Now upload this design to your slicing software of choice, print it, and there you have it, your very own hex nut screw knob! Tip: print with a vertical orientation and enable supports to it is easy to remove supports and there will be no surface pressure fractures when twisting the knob.
