spool holder vslot
thingiverse
this spool dispenser it made in two symetric parts that attach and slide along the tob vslot rod of the printer. it has been designed to associate with 4 ball bearings (8mm inside diameter, 22 outside diameter and 7mm width) there is a tolerance of 0.25mm between the rail and the part so if it's printed well it should be a nice fit. this kinf of dispanser is especially useful to gain space and for direct drive extruders. i also provide tyres for the bearings that i recommend printing in TPU for better friction.
