Large knobs to suit M8, M6, M5 & M4, and small knobs to suit M5 & M4 sizes. Use with a hex head bolt or nut.
Prints with support, can also print without support but both will need cleaning up.
Remove rubbish and insert nut or bolt.
Then snap a cap over to finish. A drop of superglue will help, but the caps are secure as is. Use the same cap without the hole for all knob sizes.
