Abrasive filament dispenser for Bambu Lab X1, X1 Carbon, P1P, Voron

This 2020 V / T slot frame is designed to dispense abrasive filament to high speed printers (ie: Bambu Lab X1, X1 Carbon, P1P, etc.) with less friction as possible. However, it works with any printer…

NOTE:

Aside from the 3 files here… You will also need my other 2 files:

1 x “2020 V / T slot spool holder converter”
https://www.printables.com/model/335739-2020-v-t-slot-spool-holder-converter

1 x “Filament guide plate for 2020 V / T slot extrusion”
https://www.printables.com/model/335778-filament-guide-plate-for-2020-vt-slot-extrusion

AND the following: 
(It doesn't matter if you use 2020 V or T-slot aluminum extrusion bars…)

2 x 1000mm 2020 v-slot extrusion aluminum bars. (Side, L and R)
2 x 400mm  2020 v-slot extrusion aluminum bars. (Feet, L and R)
1 x 550mm  2020 v-slot extrusion aluminum bar. (mid. bar)
1 x 600mm  2020 v-slot extrusion aluminum bar. (top bar)
8 x T Brackets (you can buy these or make them, there are many models around)
4 x plastic pulley wheels (you can also 3D print these)
1 x 3 inch PTFE tube 2.0 ID/4.0 OD (2.5 or 3 ID would be better)
1 x 1 pneumatic connector PC4-01 M10
M5 Hex screws and T nuts.

SIDE NOTES:

The "MT-Top-part" has a 21mm hole to allow the 2020 bar to fit in and also allow for plastic soft slot covers to be used (blue line in the photo). You'll need to use 3M double sided VHB tape and also a thin piece of 3M foam or Felt pads for the top.

The “End-Cover” and “End-Cover Remover” are optional but it helps keep everything from scratching tables, etc. To remove the end covers, all you need to do is give it a few taps with the “End-Cover Remover” tool and they will easily come off…

I've noticed that if you use abrasive filaments with 20%+ fill it might be too coarse for a 2mm ID PTFE tube in the “Filament guide plate.” So, you might want to use a 3mm ID PTFE tube for the “Filament guide plate.”

Have fun :) Cheers!

>> How to use…? <<

** Just in case you have never printed with a setup like this… For the X1, P1P and X1C:

>Pop off the top glass (not needed for the P1P).

>Remove the 21 inch feeding PTFE tube from the toolhead.

>Cut a 3 inch PTFE tube and place it in the toolhead.

> Load your fav. filament spool to the rig you just built…

>Unspool some of the filament and place it in the 3 inch PTFE tube.

>You can either manually heat up the nozzle via the menu on the LCD screen and then squeeze some filament out of the nozzle using the controls available to you...(your machine is primed and ready to use)

OR

> What I do is send the model file to print and wait till the toolhead is at the back ready to prime the nozzle and I push some of the filament in until the extruder catches it and the rest is automatic... / P.s. - the new firmware version has an autoload feature… you may want to give that a try…

>When sending the model from the Bambu slicer deselect the AMS or even better you can just unplug it entirely when you pop off the top glass.

>The "guide plate" I have is optional but it is fantastic for when you have TPU or smooth plastic spools that may unspool too much filament at a time. So, the guide will keep it under control... If you use CF or brittle filament don't bother with the guide because the filament may snap depending on the brand and chemical composition... (BTW, by design CF is MADE to snap under stress.)

UPDATE May 2023:

I have created a U bracket for the 2020 extrusion bar. This might be easier to use and cheaper than using the metal T brackets in the middle of the frame. You will need to change the size of the middle aluminum bar by ~40mm…

This U bracket uses a lot less screws per side (only 3) to secure the aluminum bar…

Cheers!

P.s. - 

** The “2020 v-slot bars” can also be 3D printed, if you want… Such as this model by chris_kwng:
https://www.printables.com/model/191448-2020-v-slot-aluminium-extrusion-profile-low-poly-m

You'll just need to resize it to your print bed size and multiply the number of parts you need to print. If you do that then either use PLA +/Pro , ABS, PC, or PA12.

** As for the “Plastic Pulley Wheels” you can also 3D print these … Such as this model by hackerbijay:
https://www.printables.com/model/58538-v-slot-wheels

** As for the T bracket or plates there are a few out there such as:
