Bicycle bottle holder, magnet snap fit

Printed the original but my printer struggled with tolerances of the design and the machine didn't like the thin edges…

I liked the design and remodeled it from scratch including my wishes.

Added three small magnets in both parts (5x4x1mm); increased tolerances to 0.3mm pet side. This resulted in a snug fit for me. I kind of reproduced original design idea.

Part is screwed to bike with M5x10 counter sunk screws.

(My bicycle was in forest last weekend and no one cleaned it so far…)
