switch cam for Bosch garage door opener

Switch cam to trigger end stop switches at Bosch Comfortlift (e.g.: 7781999110) garage door opener.

Original Bosch part (6 782 329 149) is only availble used, so I designed this to replace a missing part.

The holes were meant for cable ties, but the clips are working fine at holding the part in place, but it snaps on the chain with a very satisfying click.
