A Robo-R1 mount to hold the heater and control box for a "THORDSEN 3D INLINE FILAMENT DRYER". This is designed to mount in the slot on top of a Robo R1 or Robo R1+ printer. You could technically print it out and use it as a stand on a desk or shelf above your printer, but the support base should be enlarged or secured to a base, if you choose this configuration.
The holder will require 2 M3 x 12mm and 2 M3 x 18mm hex socket screws to assemble. You can purchase screws thread lengths that are +/- 2mm shorter or longer and it should still fit together. Don't over-tighten. Both brackets will have to be installed into the printer slot before it secured to the Controller box. Please pay attention to the orientation of the bracket during mounting (see photos), so that the bracket is as far from the central heater region as possible. The Thordsen filament dryer has an arrow on it indicating the direction of filament flow during drying, so this heater block must be mounted in the correct direction.
To hold your filament, you will want a spool that is side mounted like this:
or turn this design sideways and use just one piece with something to keep the spool on:
After exiting the dryer, the filament tube can be routed down with zip ties along the existing Robo R1 wiring to the printer head. It seems to stick just fine into the print head spring-loaded fork. As a side note, I have not tested this design yet at max Robo R1 print height.
The holder should probably be printed in ABS or a higher temp filament, as it may get quite warm during operation where it comes in contact with the dryer block. PLEASE TEST YOUR SETUP BEFORE YOU LEAVE YOUR PRINTER UNATTENDED FOR SEVERAL HOURS. By downloading or printing this design, you accept full responsibility for any damage that may result from use or misuse.

It's probably safer to print this in ABS or a high temperature filament to ensure it does not get soft when in contact with the heater block for long duration printing.
