Tinmorry Spool Adapter - Ender 3v2

Summary Please note that while tolerences on the filament is good, the tolerence on the spools is less so. I've found that these are not fitting as snugly as they used to on newer spools. Recommend either scaling or printing in PETG and warming them with a hot air gun to flex the arms to provide a snug fit once printed. TINMORRY FILAMENT SPOOL ADAPTER - 31/54 Customised using openSCAD as thingiverse is just plain broken. This is a customised print for a loose fit on a standard ender 3v2 spool holder, but nice and tight in the Tinmorry spool. IMPORTANT NOTE: Due to the design of the spindle on the v2, you cannot simply slide these on !!!! To make these work, I cut the end off the back of the tube at the cuff. I drilled a single hole through the tube to allow me to fit a split pin or similar to stop any chance of the filament spool sliding off. Combining 2 of these with PTFE tape wrapped around the ender spindle provides a nice, low friction solution without the cost of bearings etc. Ins
