This is an accessory to Madjestik58's SpoolHolder ANET A8 (https://www.thingiverse.com/thing:1624641).
Ever have that annoying problem with a new spool of filament or that spool that has a third left on it where the filament seems to want to jump off the spool. Rubber bands keep breaking. Well how about installing this braking system to your spool holder.
These accessories are specific to the above mentioned Thing. They fit into the square holes fairly well when I designed and printed them from my printer. Play with your scale for good fit. This thing consists of a Block and Rod. The Block it designed to hold a M3 nut and screw. The nut must be pressure set with the screw before putting the rod through.
4x M3x8 or M3x6
4x M3 Nuts
Pieces of friction causing material (I used self adhering neoprene)
