I needed a tall spool holder to lift the spool height higher from my desk. This was allow for other modifications already on the back of the printer (poop chute etc) and also bring the external spool height closer to the top of the machine. I couldn't find what I needed so I designed my own. This is my first attempt at CAD so all comments are welcome (hopefully positive). I was inspired by @bounetphoto Spool Holder Rescue and using the excellent @suit1337 Spool Roller. This uses the original Bambu Lab rear spool and re orientates it to use @suit1337 spool roller. This then lifts the height of the bottom of the spool to 100mm (Bambu Spool) The PTFE guide can also be used in 2 different positions depending on your setup (photos) Straight up with a slight downward angle towards the filament or to the left (about 10 'O clock angle) which points the guide straight down. Assembly only requires 2x M3 15mm screws, 2x M3 nuts and a PTFE connector. The PTFE arm is threaded for standard PTFE connectors found online and tolerances are snug so make sure you calibrate your filament.

Hopefully someone will find this useful, if not I enjoyed working on it.
