3/4" Dowel Filament Shelf

Uploaded by request; this was a 3d printed shelf design I put together in Fusion360 to help alleviate a storage concern - I have too many spools of filament, and it was difficult to see the 2nd rows on the shelves. This allowed me to repurpose a section of wall and add six shelves of storage in a space that was not really usable for anything else.

Extra requirements:

2x ¾" dowel of equal length, to insert into the holes at the top during mounting.

2x 1 ¼" screw

2x LONGER screw (length up to the installer)

Maximum Spool Size: approx. 8.5" (8.5" will touch the wall the shelf is mounted to, larger will only make contact with the front dowel and the wall).

Minimum Spool Size: 4.5", but bigger is preferable - anything under 4.5" will be prone to falling through the dowels with little effort.

Recommended layer height: I used .3mm with a .6mm nozzle, but use whatever you're comfortable with.

Recommended Filament: PETG or ABS. PLA can be prone to creeping (as can all plastics) and the one shelf I made in PLA was showing more deflection than the others after two weeks. Given that the shelves could be holding 10 or more spools of filament (10kg/22lb's or more), I wouldn't recommend PLA as a choice for this.

Supports not needed unless you're very particular about how the screwdriver and screw holes look.

The bottom hole was sized for a 1 and ¼" drywall screw, and whatever length you desire for the top. If you don't have a long enough screwdriver, you may need to get creative with the angle you insert the screw through the top holes! If you're attaching this to drywall, I strongly recommend finding the studs in the wall, or using drywall anchors to minimize risk when the storage is full. I made a mistake in measuring my dowels, which is why I have two boards visible in the main image - the boards are in the studs to reduce the risk of them falling. They've been installed since early May, and don't appear to be deforming

If you're not using the 3MF file, please bear the below in mind:

• When adding the STL in PrusaSlicer or SuperSlicer, right click and split the object to parts. This allows you to change the settings for the inside section of the shelf, if you choose. • Make sure after editing settings to make a copy of the shelf bracket, and mirror it on the X-Axis so you have one left, and one right. The holes for the dowels are NOT through-holes, so you need a separate shelf bracket for each side!

The 3MF file has these changes already in place, and also has the inner-section of the shelf set to zero top/bottom layers, and Honeycomb infill at 5% to give it a bit of style. If you don't want this, or prefer other infills, change the settings as needed.

I do not plan to make any changes to the design in the near future (Fusion360 automatically added version #'s as I made small changes). I did export and include the F3D file if you wish to make modifications. Releasing as Creative Commons Public Domain - want to make changes? Go for it! Want to change it? Go for it! Want to print a hundred for commercial use? Don't care, go for it! I literally have no real care what gets done with the design/files - it was made in a day for my own use, but someone else requested the files because they had a use for it as well. Go for it!
