Thumb Screw for Robox Smart Reel Filament Winder

Here’s a thumb screw I've created, which allows you to quickly and conveniently mount/secure a CEL Robox SmartReel against a winding insert such as this one from Heartlander.

It is made from two printed parts and an M8 nut, either full height (6.5 mm, DIN 934) or low profile (4 mm, DIN 439). After printing, remove the supports from the bigger part, insert the nut and glue in the other printed part using e.g. super glue.
