This is a simple spice rack for holding spice bottles up to 2.5" x 2.5" x 6" in size. I used #6-32 x 3/8" fasteners because I just happen to have some around.
I printed this with my Bambu Lab X1 Carbon which has a build plate size of 256mm x 256mm x 256mm using a 0.4mm nozzle at a layer height of 0.2mm. No supports are needed and I printed these with 4 walls just to make sure the perimeters were sturdy enough for the screws.
