filament spool shelf brackets

The highest and best use of 3D printers is building accessories for 3D printers.

When I first dipped my toe in this hobby, I laughed at photos of people with their extensive collection of filament spools. Now, I find myself running out of desk space and need a shelf for my... filament spools.

**READ THE INFORMATION IN "PRINT SETTINGS"** or you'll be setting yourself up for failure. There are pitfalls in this print due to the amount of stress the brackets must tolerate.

There are three different bracket styles: Left, Center, and Right. For a one-meter long shelf, I printed two Center brackets and, of course, one Left and one Right. They support a PVC plastic pipe, and the spools rest between the pipe and the wall.

PVC pipe does not have a well-defined diameter! I chose this [polished, black pipe](https://www.amazon.com/gp/product/B00MNIWDBG/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) from Amazon (not an affiliate link). It is nominally 3/4", but the outside diameter is 1.05
