Ultimate Stackable Ribbed Organizer Bowl (Round Edition - V1) | Interlocking & No-Slip

(Note: The original file names in the folders are in Turkish. "İstiflenebilir tabak - Yuvarlak" translates to "Stackable Bowl - Round Edition V1".)

This model is inspired by the unique jewelry box design found on Creality Cloud here:

While the original design is beautiful, a user mentioned in the comments that the flat bottom made it difficult to stack securely. I have completely redesigned this from scratch (100% human-made CAD) to solve the stacking issue and create the ultimate interlocking version!

The Upgrade:
Instead of a flat base, I added a 45-degree chamfered recess at the bottom that perfectly matches the top rim. When you stack these bowls, they interlock seamlessly and will not slide off each other.

Size & Scaling:

Dimensions: 101.91 mm x 101.91 mm x 31.90 mm.
I designed this at the minimum possible size for optimal utility. I highly advise against scaling it down.
Scaling Up: You can freely scale this model up! It will work even better. The recommended print settings below will remain completely sufficient and keep the model very sturdy, even at much larger sizes.

Tolerances & Files Included:
The standard tested version has a 0.15 mm tolerance. I printed this in PETG, and the fit is absolutely flawless. Since it prints perfectly in PETG, you will have zero issues with PLA.
I have also included 0.10 mm and 0.20 mm tolerance versions. All files are available in STL, STEP, and 3MF formats so you can print immediately or adjust as needed.

Print Time & Filament Usage:

Single Bowl: Approximately 2 hours 9 minutes | ~41.19g of filament.
Set of 3 Bowls: Approximately 6 hours 27 minutes | ~123.57g of filament.
(Note: Times may vary slightly depending on your printer and speed settings. Tested on Creality K1C).

Recommended Print Settings:
Due to the small default size and the wall count, the default print is practically solid.

Layer Height: 0.20 mm
Wall Loops: 3
Top/Bottom Layers: 5
Infill Density: 3% (Gyroid) - This is perfectly sufficient to maintain structural integrity even if you scale the model up!
Supports: No
