Dank's Magnificent Bowls

FDM material wants to be kept dry, and Modmike's Ultimate No Drill Dry Box System is a fine way to do so using cheap cereal containers. This immediately leads to the question: how to store said containers? Most solutions are heavy on consumed area, and light on height. My condo has 10-foot ceilings, but only 1200 square feet. I needed a solution that made good use of height.

My Magnificent Bowls can each snugly store 2x cereal containers. The sides expose 3x8 honeycomb walls, into which are inserted struts (and anything else you'd like). The struts allow for pretty much arbitrary stacking. All faces meet in chamfers for additional strength. The front and back are cut away, but support insertion of panels indicating the Bowl's contents.

Dimensions: 220x232x84mm

Design

• Why not put the struts inside, as opposed to outside?
  • The honeycomb is oriented. Supporting internal struts would mean either restricting their placement to a few of the combs, or no longer supporting other arbitrary external hookups. Furthermore, there isn't enough room--two boxes fit within the width with essentially no give on either side.

• Why no beveling on the top and bottom?
  • None on the top so you can sit something atop it.

• Why isn't the bottom honeycomb wall centered relative to the front and back?
  • So that it lines up with the honeycomb walls on the sides.

• Why aren't the placards friction-bound at the bottom?
  • We want them to be able to rotate forward upon removal of the top bolt, so that you can extract/insert spools without the placard falling out.

• How was the height selected?
  • It's as low as we can go while still presenting a meaningful obstacle to a spool. Also, at 84mm it's exactly 420 layers when printing a 0.20mm layer height.

• Why circular magnets instead of bars?
  • They can be printed without supports.
