StandBy Spool Holder (Voron V0)

Description:

After my V0.1 was build i immediately tried to mount a too large spool from RedLine, at the second Job.
So, i quickly designed this “Stand By” Holder, with a couple of MR128 bearings i had laying around. (Probably from my very first printer 😅)
These are the only additional parts needed that can not be printed. (Optionaly you could use metal or carbon axles)

The design was obviously scaled with the V0s volume in mind, and should be printable in ~5hrs on the machine - even with a rather conservative “Quality” preset.

Of course it should work with and also be printable with every other printer. Although the axles might be a little tricky to print on bedslingers.

Also: five of these should fit side by side on a IKEA LACK enclosure, as that is 55cm wide. The base of this holder is 11cm each. Not sure if this is a good idea for a MMU setup though. (I'll very likely test it at a later point)

Currently testing a first PLA prototype, but that should probably be fine.

Parts:

• 4 x MR128 Bearings OD: 12mm, ID: 8mm, Witdth: 3,5mm 
  (MR128 2RS are probably just over a €/$ each)
• Optional: 106mm lenght of 8mm metal or carbon rods to replace printed axles
• Optional: OD 4mm custom lenght PTFE tubing to Extruder/Hotend/MMU

Printing: 

• Print at 0.2mm
• 3-4 perimeter for stability
• 10-15% Infill is more than sufficient
• make sure to use brims on the "axle" Parts
  • Axles could be replaced by 8mm metal or carbon rods 106mm length
     

Assembly:

1. place one MR128 bearing on each side of each axle
2. place the axles into the base.
3. (optional) route a PTFE Tube from the back of the base to your Extruder, as you seem fit
