K1/K1C CFS Purge Chute V2

Print in ABS/ABA/PC to prevent pla from sticking inside!!!!

For extra nonstick apply PTFE Liquid/Spray

Made the other one in a rush but this one is a more brushed up version.

• Wider tube angle
• no longer requires specific screw size
• .5mm Cutout for double sided tape placement for a more flush sit

This mod does require some cutting and filing of the rear filament spool holder slot.

Items Required:

4x6mm M3 Insert

M3 Screw

Strip of Double Sided 3M Tape 

PTFE Spray

Directions:

Cut the extruding plastic piece inside your K1 Machine that sticks on the back side of the Spool holder ( I used pliers to cut most of it off then used a handheld dremel to shave it down smoother)

Spray the inner chute with PTFE Spray and give it 10-15 mins to cure.

Heat your soldering iron to 400°F and insert the threaded insert in the hole provided. Insert slowly to avoid burning or misplacement of the insert. 

Apply 3M double-sided in the rectangular cut out

Remove the Z rod and the Z motor protective cover screw. (located in the bottom next to the z rod motor

You Can Either Choose to keep or remove the Z motor Cover as you wont need it anymore

Align the exit hole with the spool holder opening you created, making sure the insert lines up with the screw hole.

Apply even pressure to the back side to ensure the double-sided tape adheres properly.

Secure everything in place using the M3 screw.

Congrats—you’re done! Enjoy mess-free multi-color printing!
