The Atlas, Filament spool holder for aluminium extrusions

Build for a Voron 2.4 but compatible with any printer that uses aluminium extrusions. Current version accommodates voron acrylic panels, will come an optional version without it for enders in the near future. Spine part can be mirrored in slicer to make the spool sit on the left side of the spool holder instead of the right, shoulder part is made to work with both left and right version of the spine and does not need to be mirrored in any scenario.

Can take spools up to 3kg but this is highly not recommended as it will flex the aluminium extrusions and should then be printed in a stronger material. Large capacity shoulder file is still provided if one wants to experiment with it themselves.

Mandatory Hardware:

• 2x Countersunk M5 12-14mm(future version with BHCS)
• 2x M5 T-nuts
• 2x M3 Heated Insert 6mm length 4.5mm width
• 2x M3 10mm
• PTFE tubing(110mm for Large & 80mm for Medium)

Optional Hardware for reverse bowden:

• M10 Pneumatic Coupler
• PTFE tubing

Instructions:

1. Insert the heat inserts into the two 4mm holes at the top of the spine
2. Insert PTFE tubing into one of the larger holes depending on if you pick right or left version of the spine. Insert it into the wrong hole? No problems, can remove PTFE and insert into the right one.
3. Insert M3 screws into the 3mm holes in the shoulder part.
4. Put shoulder up against the M3 inserts on the spine part and screw the shoulder into place.
5. Insert T-nuts into aluminium extrusion.
6. Slide the “hook” feature of the spine into the channel above the ones with T-nuts so that the 5mm holes of the spine lines up with your T-nuts.
7. Insert M5 into holes and screw the spine onto the aluminium extrusion

Optional:

1. Insert M10 pneumatic coupler into the 10mm hole above the two 5mm holes and screw it into the plastic.
2. Insert PTFE tubing through the coupler and into the 4mm hole behind it.
