Universal wall spool holder

***Thing in progress!! thinghs might be improved or changed!!
This is my design of what I think is the most universal spool holder.

It is basically a support where you can insert any piece of rod, pipe, tube or wood stick of any lenght. It is made to fit a 30mm rod or smaller (about 1.2 inches).

There are two types so you can place it where you want; betwen two walls one infront the other (print "3cm perpendicular wall") in a 90 degree angle (print one of each) or on one single wall (print "3cm parallel to wall" one normal and one mirrored)

If you need to place the right part of the "3cm parallel to wal"
