Prusament Spool Side Plug

I love the Prusament spools! Except they have one flaw…. The big indentation that the filament gets caught on. Here is a remix of a filament holder that you can use to plug that indent.  

Print 4 of these and install them flat side on inside of the spool and hexagon side to the outside to make your Prusament spools snag free! I find it's easiest to use a needle nose pliers to snap them into place.
