After a decent amount of use and failures, I overhauled the design of this part. I found the original version to be pretty flimsy and prone to tangling the PTFE tube in the spool in the event of a jam. V2 smooths sharp corners, lowers the guide, and incorporates a heat-set insert for connecting two PC4-M6 connectors.
When slicing, you'll want to orient the part with the filament guide hole on the plate and add a pause at 11.2mm so you can install the heat-set insert.
Parts needed:
- 1 M6x10x8 Heat Set Insert (I used the Ktehloy set from Amazon)
- 2 PC4-M6 push-to-connect connectors
- 4mm OD PTFE filament guide
- (Optional) Some sort of filament funnel for easier loading
I built 3D_CNC's spool holder recently and found it works great for my filament spools - large and small. I wanted a way to feed it neatly into my Bambu X1C and started with darthGinger's design for a filament guide mount. It definitely gets the job done, but the guide is free to move about in the mount. I have several pneumatic fittings, so I figured I would adapt fatttius' design to use the mount from darthGinger. Ended up using the step file from jadeqpark's spool holder remix to get the cutout right. Ended up with a nice functional filament guide to run an external spool to my X1C.
