This is a one ball bearing based and modular universal spool holder designed for Up Mini. You can use part of the components and adapt the others for other spool sizes and printers. Currently the following filamen spools are supported:
Nunus ABS and PLA 1Kg, 230-260degC
- interior diam.: 56mm
- exterior diam : 180mm
- width: 95mm
PP3DP original ABS & PLA 700g, 265degC,:
- interior diam : 52mm
- exterior diam : 200mm
- width: 56mm
- 3DPlastX ABS , 0.8Kg, 220degC:
- interior diam : 73mm
- exterior diam : 175mm
- width: 95mm
You can modify (6) for other printer type, (8) and (9) for other interior diameters and (3) for other width.
You will need:
- a cheap 6201 type Ball Bearing (32/12/10) - 1pcs.
- hexagonal cap M6 x 30mm screw - 1 pcs.
- hexagonal cap M6 x 80mm screw - 1 pcs.
- M6 nuts - 2pcs.
- some ABS/universal glue
Print all components (0) to (9) in ABS.
Fix the 6201 ball bearing between (0) and (1). using the 30mm screu and a M6 nut. Mount the nut on the small side. Use some threadlock to lock the nut,
Fix the 80mm M6 screw in (2)
Insert and glue an M6 nut in (7).
insert the ball bearing in (7) and lock it with (4) and some ABS glue.
Fix and glue the end of (1) in (6) with ABS glue and let it dry.
This is all.
Use (8), (9) or none, depending on spool internal diameter.
Use (3) for wider spools.
Insert the spool in (7), add (5) and then fix with (2).
I consider this spool holder a big improvements over the one delivered with the printer.
