Bambu Lab A1 New Top Mount PTFE Pathway for Desktop Spool Holder e.g. Creality Space Pi Filament Dryer Plus

A1 bracket to move the ptfe tube connector, enabling you to use any dry box with a top-exiting filament pathway.

I have a Bambu Lab A1 (non-AMS) as a second printer, but I don't like my filament out in the open air because I mostly use it for TPU and various types of PETGs which are more vulnerable to moisture than PLA.

I already had a Creality Space Pi Filament Dryer Plus, so my solution was to simply design a top-mounting bracket / extension that moved the existing PTFE Tube Connector out to the side of the printer, directly above the filament output port on the Filament Dryer.

Rather than designing a bracket from scratch (or going with an over-engineered version from the AMS mount) I simply re-used the mount from DoubleM's A1 Top Bar Light Mount as a base for the extension.  I made it broader so it's more stable though.  It clips in very nicely, but I'd also add a couple of cable ties just for belt and braces safety.

I used a pair of needle-nose pliers to unscrew the PTFE Tube Connector that's on the the original included Spool Holder (removal like this is totally non-destructive / reversible) and simply screwed it into the hole I've designed into the end of the new mount.

You'll need a longer run of ptfe tube to avoid a sharp arc in the filament pathway.  I couldn't find what I was looking for anywhere else (maybe it was just the terms I used 🤷) so I designed this to solve the problem myself.  It's not going to win any prizes for looks, but it's also not ugly, so I didn't spend any more time thinking about it.  A nice practical print that solved a real issue for me.

Highly recommend printing in PETG so there's a little flex in the arm.  No specific requirements for slicing, iirc I printed at 0.24 mm layer height, 3 wall loops and 25% cubic infill.  Probably overkill.
