The Microbot Fidget is based on Hiro's Microbot from Big Hero 6

Both the parts snap fit together.

Print details:

• Material Used : Prusament PLA Prusa Galaxy Black
• Layer height: 0.15mm
• Supports: No
• Brim: Yes (Only for vertically printed parts {micro1 and micro2alt})
• Infill: 20% ( I went with 100% coz I really liked the weight)

Tested it at 50% scale too and works fine. Scalability should not be an issue.

The model has been designed to have a satisfying tactile snap at 90 degrees angles.

Note:

There are 2 files for the socket joint part, print the recommended version and stick both halves using some superglue.

I haven't printed the alt version as I feel that there's a high chance of the part breaking (layer separation)
