Proto Pasta Spool Sleeve
thingiverse
The spool holder I use on my Printrbot Simple has a somewhat sharp point at its top, which doesn't work very well with the new cardboard spools that Proto Pasta uses. To solve this problem, I designed a simple sleeve in Tinkercad that can be inserted into the spool to reduce the friction between the cardboard and my spool holder.
