Update: checkout my new manual filament loading system that works with any printer and also dry boxes: https://makerworld.com/models/478169 

---------------

I love my A1 Mini - but I dislike manually loading filament by pushing it up the long Bowden tube. I also am not keen on the filament is handled in general - as it's too prone to tangles. (I do not have an AMS lite).

• This model addresses both issues helping quickly load filament while routing the bowden higher and keeping the filament in check during printing preventing tangles. 
• You can also see the handle move while loading and printing which helps know things are working well.
• It's easy to install, mounting to the stock filament holder mount and then allowing the spool holder to mount to it.

It can also be used with any other printer if you use the stand for it here but I recommend using my manual filament loading system instead your can find here :  https://makerworld.com/models/478169   

You will need:

•  3x 608 bearings
  • one for each gear and one for the handle. 
• It also supports using a PC4-M10 connector to hold the bowden tube in place - 
  • but you can use a friction fit alternative in the file instead. 
  • It's easier to fit these to the part first before adding the gears on.

Printing and assembly instructions

• There are two versions of the feeder body in the file
  • the original one with the pins that hold the bearing built-in and 
  • a new one where the pins are separate - I recommend this version as it means you can get a better fit depending on your tolerances.
    • On this plate, there are two sets of pins - one slightly narrower and one slightly wider so you can choose the best fit for your bearings. 
    • If you print this - check which pins have a good fit for your bearings - you do not want them to be loose in the bearings as the gears will slop about - then push them into place on the feeder body
      • Long pin on the right, short pin on the left.
• Insert the bearings into the gears
  • The fit for them is purposely tight, though its a bit looser in the current design that the original design
  • If a bit of force is needed put them in place in the gears, turn the print over then put your weight on the gears and they will click into place
  • If you want to use the handle put a bearing into one of the 4 holes of the big gear and then slide the handle piece into the center of the bearing
• If you are using an PC4-M10 screw that into the top of the body before putting the gears in place as that is easier. 
• If you are using the printed insert instead put it in - it should screw in, but if not lightly tap it into place
• Then put the gears on - the smaller gear first on the left, the larger one on top on the right. 
• Then slide the adapter block onto the A1 mini spool holder bracket
• Slide the body onto the side of the adapter block
• Slide the original spool holder onto the back of the block.
