horizontal spool holder

Due to the lack of practicality of closed printers, I designed a horizontal spool holder.

I made a first version with a single bearing but as I didn't find it stable enough, I made a V2 with 2 bearings.
I put the 2 versions, the V1 is more economical in bearings and the V2 more stable.

You will need :
4 M3x8 button head or socket head screws
1 M3x8 flat head screw
1 or 2 608ZZ bearings
