This mount is for Bambu Lab’s 4-into-1 PTFE Adapter (https://us.store.bambulab.com/products/bambu-4-in-1-ptfe-adapter) that allows 4 separate inputs into the toolhead of the X-series/P-series printers.

My particular setup is a Bambu P1P with ARC enclosure kit, but it should work on any P-series or X-series as long as your current modifications do not cause interference.

I discovered that mounting the bracket directly to the back of the printer put the PTFE input tube at an awkward angle that caused friction issues when feeding the filament so I designed this mount to solve that issue. Many different angles and lengths were tried before settling on this final design. I have over 100 hours of printing with this mount and it has performed flawlessly. The mounting holes allow the bracket to be adjusted slightly in the lateral direction before tightening down the M3 bolts.

My 4 inputs are:

1) External Spool mounted on the left side of the printer

2) AMS input fed directly from the output of the AMS Filament Buffer (https://us.store.bambulab.com/products/filament-buffer)

3) Wall-mounted External Spool used for 3kg rolls

4) External Spool fed from a Sunlu S2 filament dryer (used mainly for printing Nylon & PC)

***The mount was designed to use a total of three M3 bolts and one M3 nut***

***I also added four individual PTFE Tube Connectors (https://us.store.bambulab.com/products/ptfe-tube-connector) to make it easier to remove the PTFE tubes if needed to clear a stuck piece of filament since these connectors are much easier to remove than the ones installed on the 4-into-1 PTFE Adapter. These connectors are not necessary, but could improve useability if the back of your printer is hard to access, such as in my setup.***
