Agile Spool Adapter (20mm)

thingiverse

I needed a reliable spool adapter to mount standard 1Kg spools onto the [20mm pipe spool mount I designed](https://www.thingiverse.com/thing:3095951) for my Geeetech I3 Pro B. I tried several designs found on Thingiverse, but none met my requirements: some were unreliable, slipping out of the spools at inopportune moments, others were too fragile, breaking apart after a single use. Here is my solution, featuring the *Full* version with grab slots for fingers, making it easier to attach and detach the screw. The thread is robust and forgiving, with an increased tolerance of `0.6mm` to accommodate print errors. It requires minimal setup: just ensure you don't produce excessive stringing and decent short overhangs (even at a `60°` thread angle, which lasts less than `10mm`).
