Leveling bracket for iPhone 12

As any devoted road cyclist knows, the saddle angle is critical to finding an optimal riding position. This and other key dimensions are best obtained by visiting a local bike fit shop. Once you know the key dimensions and angles, then it's time to setup the bike accordingly. Most things can be just measured with a tape measure, but the saddle angle would require a special (read: expensive) meter.

Luckily I found a nice [angle meter in AppStore](https://apps.apple.com/fi/app/bubble-level-spirit-level/id1547834136). Final problem to tackle was how to keep my iPhone 12 stable on a flat surface that rests on top of the saddle.

I ended up modifying the source 3D model by cutting out unnecessary parts and joining it to a new base plate that features screw holes for securing it to a piece of plywood.

This project was a part of my bike's tuning to the upcoming [DJBB 2024 event in Jamaica](https://discoverjamaicabybike.com). Hence the text "DJBB 2024" in the base plate ;-)
