Giá đỡ cuộn chỉ gắn bên hông cho K1 Max

K1 Max spool side mount for use with the original stock (rear mounted) spool.

I printed the spool holder by Fulvio Folegnani and it works great.

But it wouldn't work with smaller spools, so I threw this together in Tinker Cad (still Learning FreeCad). There is no need to remove the regular spool after it's been extracted out of the Bowden tube. This model mounts above the other spool holder, using 2 side panel screws. The top panel screw was replaced with an M3x6mm and the other was the fan screw, and it was replaced with an M3x14. I wanted the screw holes tight, to reduce the play, so it may need a little extra push to get them in. 

1 - M3 x 6mm Screw (Side panel to top rail replacement)

1 - M3 x 14mm Screw (fan screw replacement)

Both screws are round head which I had on hand. Not the flush type.
