Most of parts are printable. PLA recommended (except „rod“) - this must be printed horizontally with PETG. With this upgrade - printer is 508 mm high (without original spool holder).
Other parts that you will need:
1x PTFE tube 2/4 mm x 1 m
1x M3x6 bolt with cylinder head
3x M3 nut (max 2,4 mm wide)
2x M3x8 countersunk head bolts
2x bearings 22x10x6
Few zip ties
(Holder can be fixed in profiles - 2x M3x12 bolts, 2x T-profile slot stones/printed ones).
HOW TO ASSEMBLE:
- Put two bearings into „holder support“.
- Insert M3 nuts into holes next to berings.
- Insert „rod“ through bearings.
- Put „holder support“ to printer profiles (do not forget to insert back and front base parts). (You can add profile stones + M3x12 bolts).
- Tighten „bearing cover“ in „holder support“ with 2 countersunk head bolts.
- Assemble PTFE tube with 2 „PTFE tube holders“ at right printer frame edge (Ends of PTFE tube must be little bit longer than the frame).
- Tighten it
- Insure PTFE tube with zip tie at right bottom corner hole of frame (You can fit 2 zip ties here).
HOW IT WORKS:
Put „spool holder“ into your spool and insert it to „rod“. Try to rotate with it. Than just push filament through PTFE tube to extruder.
When you want to change the material:
Push filament back through PTFE. Lift up the spool with „spool holder“ and twist it. „Spool holder“ should drop down.
I will be glad for your feedback
