EcksBot Spool Hook

Designed to mount onto or assembled into the Ecksbot.
Inspired by, but not derived from:

scad file has switch to change mount type.
spacer=0 Clip-on mount
spacer=1 Use Hook in place of Spacers in Ecksbot build. (Untested!)
I recomend using a filament guide (thing:16267 V4)
Enjoy
Note: Released Flies more rounded than Pictured Prototype.
Update: Works with new EckerTech spools!
