I really like this practical drill clamp, and I'm very grateful to Scarou!

However, every time I take off a drill bit, the clamp will slightly shake, which bothers me a bit. So I installed a rotating shaft at the end of the clamp.

Edit note:
I've readjusted the dimensions and hope to achieve a better fit. At the moment, my 3D printer isn't working properly :( So I can't conduct actual tests yet. Once the printer is repaired, I'll personally verify it and further optimize the design.
