Filament wall mount with MMU buffer V3

Wall mounted spool holder.  The spool mount section lifts up so you can place these next to each other and still change the spool.  Includes a prop for the arm to make changing the reels easier.

The filament runs from the spool, into the PTFE tube, up the back of the mount, around the wheel down the other tube and to your machine.  When ejecting from the MMU the filament runs up the back of the mount and pops out the top, saving it from getting tangled.  The internal walls slope towards the disc, ensuring the filament lands on the disc every time the filament is loaded back to the machine.

This is an evolution of my original design:-

I found my original design caused too much friction so this is my solution.  If you're wondering what happened to V2, it simply didn't work!

I went to smaller connectors as it stops the tube getting pulled through.  

This new design works well and I've run a number of prints without issue

Requires:- 

2 PC4 M5 connectors 

1 M3 20mm bolt/screw

2 sections of PTFE tubing.  One approx 6cm, one long enough to reach your machine.

2generic screws for attaching to the wall.  

I used 3mm ID clear PTFE, this provides less friction and allows you to see what's going on.   I have found that if the piece that leads to the reel actually touches the reel it can cause jams.

The disc screws to the wall section with the M3 bolt.  The disc should spin freely on the bolt but may need the hole running the through with a 3mm drill bit for a little extra clearance.

Both connectors now live on the bottom of the unit, to get them to sit straight I found it easiest to use a socket set.  Just be careful not over tighten them!

When screwing to the wall ensure the screws sit flush so your filament doesn't get caught the holes are chamfered for this reason.

I printed with 3 walls and 5% infill.  Orientation as per the 3MF files and no supports are required.

I think installation is straight forward and the pictures probably explain it better than I have here.

Any questions please ask.

If you make this please share pictures, It gives me a warm fuzzy feeling to know someone else has liked my work enough to make it!

This design has taken me many hours of refining and used a fair bit of filament to get to this stage.
