Ord Bot Spool Holder

Modification of design by blah_59 by the same name. I took out all the extraneous parts that make it difficult to print and require support. Support structures for this file are embedded into the file, so print without support. It is designed to use 5mm button head screws at the top to mount it to the makerslide and either a 5/16" or 8mm rod to hang the spools on.
