80mm Printrbot Spool base piece

thingiverse

Provides a wider base (80mm) for the Printrbot Spool Holder, but not as wide as markbrannan's Spool Holder "upgrade." All of the spools I have bought are between 76-79.5mm wide, which just do not fit in the original spool holder that works for the 72mm wide Printrbot spools. Instructions I've also modified the holes for the nuts to be slightly larger and the posts that go into the side to be slightly smaller because when I printed it out in PLA, the nuts wouldn't fit and the posts needed to be carved down. I think part of the issue was that I used PLA which if I understand correctly, doesn't shrink as much as ABS. Next iteration will have the text bigger and perhaps include pegs that can hold a double set of bearings so that I can use the narrower Printrbot spools as the wider aftermarket spools.
