I love keraynopoylos's design, but using keraynopoylos's great spool holder I was still getting the odd issue due to the spool sticking/not turning. I want to resolve that, because it sucks to ruin 18+ hour prints.
This is just a concept for now. I am waiting for the bearings to arrive in the mail.
"left" and "right" are my designs to allow for an 8mm metal or wood rod across the top.
"middle" still needs to be extended to allow for various spool sizes and mgx's spool holder.
"top" to be replaced with an 8mm wood or steel rod. I could do a design for one in plastic too. Should be easy.
Update - 2014-09-28:
I will not be working on this anymore since my printer is now on a wire shelf and I am working on hanging the spool on the shelf above.
