A Filament Return pulley for Vertex Delta

Some brands of filament spools (e.g. Renkforce 500g)have grooves and stuff like that where one might run into problems with the way vertex delta unrolls the filament.
(for example: https://www.conrad.de/de/filament-renkforce-pla-compound-175-mm-bronze-500-g-1528342.html)

I made this thing:

Which should help tu unroll the filament gently from the spool.


Hey there,

I just posted an updated version of that thing on Thingiverse.
