Barbell Lock Collar

thingiverse

This is a locking collar for a standard barbell, expertly crafted with 30% infill in ABS. I had hoped to print it with flex, but time constraints prevented that. Instead, I fashioned a makeshift grip by cutting rubber and gluing it onto the center spacers of the collar. Surprisingly, this works quite well. However, you may need to download the STL file, modify the "side_grip" piece, and adjust its thickness based on the specific rubber you choose. To complete the build, four #6-32 flat head screws measuring 12mm in length are required.
