Manual filament feeder.

It is similar to the automatic AMS system, but here the filament is loaded manually.

It is suitable to wind the filament from an external filament storage or dryer directly to the printer with a long ptfe tube. Attached to the container, the filament can be delivered to the extruder in a shorter time thanks to the transmission. With a Y or multi-inlet ptfe manifold, multiple hand feeders can be used for multiple rolls of filament. With the help of A, the filament only needs to be wound back to the distributor y, and when loading, only the last 40 cm must be loaded to the extruder.

I ordered the adapter from Amazon. link:

I cut the original spring to 17mm because I found it too strong for the printed axle.

I melted M3 threads into the holes. I used 16 and 30 mm M3 screws.

I made a spare small gear without a shaft, into which a steel shaft with a diameter of 5 mm can be glued.
