A simple model of a lathe collet to fit a Jet desktop lathe with a 1 inch 8 TPI shaft. 

All parts should print without support at 0.125 layer heights. Mine were printed with a 0.6mm head on a Prusa i3 MK3. Give these at least a 2mm wall thickness and 25% minimum infill for appropriate strength. 

 

UPDATE 2023-11-14: The overall size of the assembly has been reduced. The nut doesn't stick out as far from the collet face so there's less clearance needed to hold the part. The collets themselves have also been chamfered to allow parts to slide into them better. Additional chamfers on the inside of the nut  should center the assembly better.
