Shimano SPD-SL Cleat Cover

Here's a cover for Shimano SPD-SL cleats.

I printed these with following settings:
- 0.2 mm layers.
- 30% infill.
- 0.8 mm shell thickness.
- 1.5 mm bottom/top thickness.

(It's a work in progress, so I will follow up with a revised version when the first set of covers wear out. Feel free to suggest improvements.)
