Shaft Collar Compression Fit

This is a Shaft collar that uses Compression vs a screw. Advantages are No tools needed although you can and it is less likely to break from tightening.
It can be scaled for any shaft size you need or you can resize the bore and keep the overall size.
Works great. A touch of grease on the threads will make it work very smooth and release easier. avoid grease on the inside bore.
Print the two parts individually to avoid stringing.
No support needed. best if printed .1mm layer height.
