Filament Sample Spool Winder

thingiverse

This tool helps you with winding filament for trading samples with your fellow 3D printing nerd. For a filament exchange we had to portion several meters of filament from larger spools. Doing so by hand was quite arduous and took a lot of time. Use this spool with a cordless drill to quickly create sample rolls of 50-150g that fit well into 200x250mm vacuum bags. The front plate is clipped on to easily remove the wound filament. Assembly requires two 8.4x30mm washers, one M8x50 screw and one M8 nyloc nut. This Thing might be printable without support but to provide clean edges for the clips I used support enforcers for the relevant parts of the model. Print with PLA using 0.3mm layer height, 3 shells and 30% gyroid infill for sufficient mechanical stability. You might want to use a tiny amount of glue stick under the inner part of the clip wings to prevent them from detaching while the top part is bridged.
