This manually operated TPU filament feeder, with a diameter of 1.75 mm, can be integrated into the line to connect an external filament spool. To avoid having to disconnect the hose connections, the box can be installed between the external filament spool and the Y-connection (see picture).

The box is almost completely sealed to prevent the ingress of moisture. If you would like an update with a commercially available desiccant bag, please leave a comment.

No tools are required for installation. The handle simply needs to be pressed into the bracket - using a hard object or vice if necessary. The axles also need to be pressed into the gears, which may require some force. Place the gears in the box first and then insert the axles. The same applies to the crank, whose gear wheel has a driver that must be positioned correctly.

Once the filament has been inserted through one of the side openings and placed over the three gear wheels, the two boxes can be connected. By turning the crank, the filament is automatically pulled into the other opening, eliminating the need for tedious manual threading.

As soon as the filament is pulled through and the boxes are connected, they can be fitted to the tubes. Then push the two sliders through from below. This may require some force (see picture).

Printing and assembly was superb as was feeding the filament intobthe printer. However, for me with X1C and TPU with Shore 85A the resistance added by the device was too high during printing and severe under-extrusion was the result.

@user_4064080046

Did you insert the two lower brackets so that after use you can push the upper and lower gears apart again to have less resistance

Replying to @user_4064080046 :

Yes I did that My hypothesis is that the curved entry into the box creates too much resistance for soft filament with Shore 85A

Could a larger hole diameter for the filament help with feeding and retrieval then I could make it 0.5mm larger for less friction

very good, simple and quick. if i use PLA i switch it with a PTFE coupler. the manual loading is OK for its simplicity.

works great just a but hard to get together

at first this was a great solution for feeding my TPU from my drybox after a while i started getting horrible underextrusion. I tried 3 different drybox rollers and still had the problem. Eventually I tried removing this and now my TPU prints perfectly. From what I saw the issue was the downward slope of the enter and exit tubes causing excessive friction.

@meterman81

so do i print it in tpu or does it feed tpu

The designer has replied

@meterman81

am i suposed to use 95a or 85a

@user_4064080046

it is printed in PLA and supports TPU it can only support TPU

tip top for my x1c I try , next level add little motor and switch for help output from dryer

@RayHbigdog

plate one won't print . I get an error saying slicing failed? the 2nd plate printed without a problem. any ideas?

@klos

I’d recommend opening in Bambu Studio; it looks like two of the parts on plate 1 are in the collision zone for the p1/x1. Adjusting the two part locations on the bed to prevent overlap (it’s only a tiny amount), and things should print.
