A filament spool rack for the multiboard system.
I use the 13mm multiboard bolts to fix my brackets.

The wooden pole used is a broomstick which is 23mm diameter. There is a left, a right and a in-between support frame (passthrough). You can use one or more of these passthrough brackets for extra support.. I also included my driver for bolts. I found this driver on printables very helpful also.
