*** Update: Added new version with a ring around the outside.  

This is a print in place gear fidget spinner in a Triangle shape. The gears are held in place in the middle by a V grove preventing them from falling out. There are three print options, including a single color version, multi-color version, and multi-color multi-object version. For the last one, I have found that with the changing of filaments, it is better to print multiple at the same time.

The model should be able to be scaled up or down based on your preference. Keep the X/Y scales in sync, but the Z scale can be changed independently based on your desired thickness. 100% in all directions was too big to hold between two fingers and spin easily. 80% works for people with larger hands, and 60% works well for most people. In the image, the black one is 100%, blue is 80% and multi-color is 60%.

The model is made with a high number of walls in the outer part to help add weight to the model so that it spins more.

The print spins freely right after printing, but a little oil would not hurt it.  Based on some other suggestions on here, I have found that “Super Lube Synthetic Oil” does great things for these types of models.  [https://www.amazon.com/dp/B000UKUHXK](https://www.amazon.com/dp/B000UKUHXK) 

** The print times above are based on all versions of a given size (multi-color as well as single color). Single color prints in about 2 hours.

** The carbon fiber texture on the print is from the print plate that I used, and is not part of the model.

** V2 was made to improve the clearance in the model.
