I really love spool holder on the side designed by BC designs, but because bearings are situated outside the roller it makes it automatically much longer than needed. This design is about 25mm shorter than original one!

I also decided to make the roller shorter than most holders on the market where standard seems to be 90mm, from my observations all spools I have, fit easily on 70mm long holder, and that's my idea to make it as short as possible to reduce stress on mounting point between roller and mount on printer.

What you need is:

• M5 x 80 bolt (hex style) - I used this one, you can check the data sheet for reference.
• M5 nut
• 2 x 6000ZZ bearings (25mm outer, 10mm inner, 8mm thickness) - can be 6000-RS, / 6000-2RS just different sealing. As an example you can check those on AliExpress.

Recommended printing in standing position, as on example profile attached here.

If anyone need longer one I will consider to add modified version as well! Just message me in comments or DM.

Yeah I know on photo my bolt is too long - it's 90mm, that's why I used extra raiser, but I will replace it once new bolts will arrive to me ;-)
