Garage door opener chain end stop

Replacement chain end stop for Bosch COMFORTLIFT GTF-27L / GTF-40L. The clips are more stiff than the original, so it is a more difficult to mount, but it should also sit more securely. UPDATE: So far I have only test fitted an earlier iteration of this. Cura tells me that there are errors in the updated / current version, but it slices and prints just file.
