Filament Spool Shelf Bracket

Shelf bracket to support a shelf to hold 200mm filament spools. This one requires one piece of 42mm x 16mm wood and 2 x 20mm rod. There were lots of other designs I liked but none that used a backing board as a mount.

**Why these sizes?**
I chose these sizes because the wood is a standard size here in Australia for skirting and I had some 20mm tube from some old curtain rods.

**Why use a backing board?**
I wanted to use wood as a backing board an support for two reasons.

1. The supports behind the plasterboard in my house are quite irregular and I didn't want the shelf supported by the plasterboard.

2. I wanted a something to stop the spools marking the walls.

**Printing**
0.24mm Layer height with 4 walls and 4 layers top and bottom. I only used 5% infill to reduce print time as most of the strength comes from the thick walls.
