Download Free 3D Model Squeeze clip for filament spool spindle / axle 3D Print Model

Summary
For my Anet A8 I wanted a quick release alternative to the supplied M8 nuts, so I designed this squeeze clip. To use just squeeze the arms together slightly to release the grip on the rod and slide off. They won’t grip as well as a nut with lock nut, but it works fine to hold the spindle in place.
I made 2 sizes one for the stock M8 threaded rod with an inside diameter of 7mm and a smaller one for a 6.4mm guide rod I salvaged for a scanner, used for a different spool stand.

I used a wide skirt to help with bed adhesion, My printer isn’t keen on small parts and I lose accuracy without the skirt. Your printer may vary.
The needed supports are all built in and will snap off. I print the clips with 4 lines on the walls / shells hence the 0% infill. I tried printing with thinner walls and 20% infill, but the clips were prone to snapping.
Post-Printing
Trim any skirt and stringing. The support in the gap between the rings that allows the clip to flex, will break free the first time the clip arms are squeezed.
There may be a small amount of support material that needs freeing up from the gap. I used tweezers and a craft knife.
