The file 'Curl Bar Star Lock Collar 3D Printer Model' is (scad,stl) file type, size is 396.2KB.
A screw-on star lock collar for a 1-inch weightlifting curl bar. The original metal one was too loose (came unscrewed when lifting), but this one can be printed a little tighter.
SCAD file attached for customization. Print with extra layers & infill for strength. Scale a bit smaller if not tight enough.
(Updated 10/27/24 for better fit and smoother edges.)
