Yet Another Spool Holder

I've had more luck with hanging holders than rollers for extra spools; the rollers can creak and spools may occasionally fall of or just not fit right in the first place. 

This mounts with two #6 wood screws and holds two 1kg spools if it's mounted straight or slightly angled up. If you have 16" joists, you can fit two holders facing one another with juuuust enough room to get them in and out.

No special printing instructions, other than a note to keep the infill percentage high. This is sliced for a 0.6mm nozzle, which brings the print time down to about 4.5 hours.
