Modular Stackable Shelves - Flexible Heights

I really enjoyed the original model that dewgenenny created. However, I wanted to have more flexibility with the shelves' height and tighten the tolerances quite a bit for a snug fit, as the original seemed a little loose.

I revamped this so the pillars/legs are separate from the shelves. You can print the legs and use them as is in single heights of 76mm,100mm,126mm, 250mm. You can combine them to go even higher if needed. This allows for a highly customizable setup if needed.

No special printing steps are required. However, there are some things I will call out.

I didn't use any supports.

I used a brim around the pillars (especially the tall ones to ensure they did not fall over).

For the legs/pillars, I increased the infill to 25%, but you don't have to in most cases. I went that way to be safe with the tight tolerance and didn't want to snap when I lightly twisted them in.

Printed with Gyroid infill pattern.

Important

I have a .1mm tolerance between the diameter of the leg insert and the receiving hole of the legs/shelves. My printer is dialed in really well, and this worked perfectly with my PLA prints.

You may need additional clearance for the leg/pillar. I intentionally made it a very tight fit.

When inserting the legs into each other or the shelf portion. BE CAREFUL and lightly twist as you slide in.. Don't overdo it, or you could run the risk of breaking at a layer line on the leg. I have assembled 8 units now with no issue taking my time to insert the legs. The best part is the shelf does not come apart easily if you move it, but you can disassemble if desired.

The pictures on this upload are of a print in Bambu Labs Matte Charcoal PLA.

I will work on updating my Fusion 360 file so I can upload it with the parametric ability to change the height to measurement and export. For now, it's just the sizes listed above.

I hope everyone enjoys them as much as I have.
