filament spool shelf brackets

thingiverse

The greatest potential of 3D printing lies in crafting accessories specifically tailored for 3D printers. When I initially explored this hobby, I ridiculed photos of individuals with their extensive collections of filament spools. Now, I find myself running out of desk space and needing a shelf to store my... filament spools. **READ THE INFORMATION IN "PRINT SETTINGS"** or you'll be setting yourself up for disaster. There are potential pitfalls in this print due to the amount of stress the brackets must withstand. There are three different bracket styles: Left, Center, and Right. For a one-meter long shelf, I printed two Center brackets and, naturally, 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". If you want to use pipe with a different OD (it still might be labeled 3/4") you'll need to use FreeCAD and change the size of the pipe slots. The screw holes are designed for #10 screws that go into hollow wall fasteners. If you use smaller screws, make sure to use washers or the screw heads will pull through the brackets (even if you resize the screw holes first).
