Phil's support, but better rollers.

You will need to use a drill and drill out the original holes for the push pins.

I use this design now. It works way better. https://www.thingiverse.com/thing:2221639

I printed the original without reading the comments. That was a waste. Rollers spun with no load on them. Great idea, poor design.

I did like the brackets and hate to waste things. I also printed another spool holder for the MK2, but I do not like the spool hanging off the frame.

So, I used the roller, bolt, nut and washer from that design, and a drilled out the holes in the bracket to fit. Thing spins like a dream now.

I have not run a spool out yet on this stand to see how it does. There is so little friction to roll it, I don't think it will be an issue, but I will see later.

I should add that the bearings are the 608's.
