A1 Mini Spool Widener

When I use cardboard reels on my A1 mini spool holder they fall off when the reel has a small amount of filament left and cause filament feed errors - this model is a simple device to widen the end of the spool holder by about 10mm to prevent falling off. The end piece glues onto the spool holder and the two flanges are glued to it to hold everything in place
