"Nutcase" — Decorative container for pens, tools, plants, etc.

Works well for desk utensils, tools, or as a planter.

Update 12-18-22: 

• Added new version that uses magnets instead of a screw mechanism to hold the parts together. The screws work fine but have a bit of stringing in the threads. Requires 8x3mm round magnets (e.g., https://www.amazon.com/DIYMAG-Refrigerator-Magnets-Premium-Brushed/dp/B07B3SDRCP). 3 for the base, 3 for the lid, 6 for each element.
• Added new version that has no locking mechanism. To connect parts permanently, use superglue. Best version to scale up and down.
• Increased the height of the knob, to make it easier to remove the lid. 

Printing and Assembly

Modular design. You need at least a base and one element, but more elements can be easily added by screwing them together. The lid is optional.

Print setup is straightforward. I printed everything with a 0.4 mm nozzle at 0.2mm layer height. I assume a 0.6mm nozzle would work as well. No supports required, but the pin needs a brim. See lid.3mf for the setup and settings I used.

The threads in the screw connector version may show some stringing, in particular on the side away from the fan. I just used an Xacto knife to clean things up a bit.

To assemble the lid, screw the knob onto the lid, and push the pin through the hole in the knob base, when lid and knob are properly aligned. The pin may require some force to go in, some lubrication may help, or reaming the hole. Be careful not to break it (which of course I did right away). The pin is not really required. You can of course also secure the knob to the lid with some drops of superglue, or just leave it as is. I only added a pin to prevent the knob from unscrewing when removing the lid.

Base, elements, and lid should screw together easily. Give it a few rounds of opening and closing to make it go smoother.

For the magnet version, make sure your magnets are properly oriented and attract, not repel each other. Nothing is more aggravating than discovering at the end that one of them is oriented wrongly. Use a drop of superglue for each magnet to keep them from coming out. I also suggest using at least 3 perimeters for printing the elements.

The model in the photos was printed with Proto-Pasta Brass HTPLA, andvinegar, salt, and ammonia used to create a patina.
