This is a simple, no-tools, no-screws, desktop spool roller/holder.

Just need to print 4 of them and then snap the halves together with four 608 type bearings.

Note:  this is not my design.  I found it years ago, wanted to print another one recently, and couldn't find it anywhere.  Thankfully i was able to dig up the old stl on my hard drive.
