Filament Shelf Brackets - 1 Inch Dowel Rod

These filament shelf brackets are designed to use two solid wooden dowel rods (1-inch [25.4 mm] diameter). The rods recess into the left and right side; and snap securly into the optional center support.

The files include two sides (left and right) as well as an optional center support for use with longer dowels. There is also a screw hole cover for asthetics, which can be removed later if shelf removal is required. I used 6 foot long closet rods with the center support. These can be found easily and are very cheap from any big-box store. Fully loaded, this version will hold up to 27 spools (about 60 lbs), the rods are very sturdy and could support more weight easily.

Use only left and right side (up to 4 feet)
Use left, right, and center support for varients over 4 feet.
(I would recommend using multiple center supports for variants over 6 feet (At least every 48-inches)
-----------------------------------------------------------

Print each part on its side (left and right side should face opposite), I would recommend at least four perimeters and 25 % infill. (I used Polymaker PETG, with Gyroid Infill, and they are extermely sturdy). I printed without support and there was no issue.

To mount, I used #9 x 2-½ construction screws in studs where I could and drywall anchors when studs were not present. If installing with a drill, make sure to set the clutch and not over-drive the screws. Mine are very surdy without washers but they could be used to distribute the load for added security.

The srew holes are 6.5 mm in diameter. The recesses for washers are 18.5 mm in diameter.

The mounting can be done alone but having a second person to assist would be helpful. I used a laser level and marked/drilled all screw holes. I mounted the left and center support, added the rods, added the right side support and screwed it in.
