PrintrBot Spool Holder revision
thingiverse
This is a variant on Emmett's PrintrBot Spool Holder, which I really like a lot. It's the best spool holder I've seen because it integrates securely onto the printer without dangling the spool off the side, which can interfere with high-Z builds. I used it for several months until it broke when my PrintrBot fell over during transport in my car. Before printing a new one, I made these modifications: - Rounded head - Adjustable guide arm height - Reinforced guide elbow **UPDATE 13 December 2015:** New changes in version "tkb2": - Variable arm thickness - Improved arm filament guide shape using sphere hulls - Added various 1/4" mounting holes at base and on shaft - Guide elbow converted to a nice sweeping curve instead of cylinder
