built for 8mm threaded bar.
I was starting to lack space on my desk and came up with this.
The nut holder will need the nut to be pressed in its a little tight but does work well
as I've stated this is a work in progress and I will be making improvements to this as I find problems. one problem I've found is one holder isn't enough to hold the spool level so I've now included a mirrored version for the other side this will enable a longer bar .
I will also be including some modifications to the spool cones by adding bearings.
