I bought some PLA on a spool that didn't quite fit my laser-cut spool roller. I really wanted to print something that would take a while and I didn't want to babysit the printer all night.

I had everything I needed to make this laying around the Schlaboratory - so I designed and printed the bases.

Easily adjustable for any width spool.

======== UPDATE ========
PLA can be tenacious stuff, and when you get toward the end of a spool, you may find that the spool doesn't have enough mass to stay on the rollers if you are feeding sideways. Initially, I ran the filament UNDER the front threaded rod (with some padding to keep the threads from gouging), but I made a guide to mount under the front element that helps to pull the spool of filament DOWN, onto the rollers.

I don't know if this really qualifies as RepRap, but it is technically part of the printer system, and it's constructed in a typical RepRap manner.

You will need:
-2 - lengths of threaded rod (8mm or 5/16) I used approx 7-1/2" or 190mm

  • 4 - 608 bearings
  • 4 - fender washers
    -16 - nuts
    -16 - normal washers

The photos should explain assembly better than anything I might write.

You may have to wrack (twist) the assembly to persuade it to sit flat, but it will stay flat after that.
