Overly complex solution to a problem I created. My spool dry box is mounted above and behind. This eases the angle.

Well, another specific solution; this time to service a problem I created for myself ;-)
I am 70% happy with it but I would consider this an overly complex draft solution…
My dry box is wall mounted to the rear of the printer. I had to add a pulley/sheave directly under the dry box and designed this to ease the filament approach over the top from of the printer.
Its not perfect and it is unlikely to be my final design but if it helps you with a similar problem, feel free to use it.
Uses a 100mm by 8mm rod and two 608-2RS bearings. I forgot to add access for assembly and had to drill a 10mm hole in one end to get the rod through to the bearings and roller.
Printed in PETG but PLA would work as well (was not sure about roller wear at the time)
