Knob quarter-20 stubby

thingiverse

I've recently discovered a design that barely qualifies as a remix, but it caught my attention with its clever "T-Slot for 1/2-20 carriage bolts" feature. I printed several of these knobs, but what I really needed were shorter versions to secure templates using quarter-20 hex head bolts into threaded inserts on my workbench's waste board. The shorter length keeps them out of the way without any clutter. The design's softened edges are also a welcome touch - they're easier on my aging hands. When inserting the bolt, it fits snugly and stays securely in place.
