Command Strip Spool Holder

2019.11.07 UPDATE - I started having the command strips give way (they seemed to have dried out or something. Maybe they were at their limit for holding two 1kg spools so I did a quick redesign to !!double!! the mounting surface. I have yet to print this redesign because I just reattached these brackets with new Command Strips but maybe one day I'll print these. Until then I'll just preemptively replace the command strips after about 18 months.

I am a renter and didn't see any spool holders/racks/brackets that could be mounted with command strips instead of screws. So I designed my own. These are designed to use the "medium" 3M Command Strips (tm). I've hung about 1.5kg off just one bracket for a day. I am using a pair to hold two 1kg spools of filament and I'm using 20cm of 8mm threaded rod. If they turn out to fall/pull off I'll redesign them to use the large Command Strips (tm).

ps: Thanks to AristoDesign who's design (https://www.thingiverse.com/thing:2755427) was the inspi
