Schartec Prime 600 Speed garage door opener - repair parts for drive trolley

The trolley of the garage door opener was damaged - there are two parts inside needed to engage the trolley to the belt drive that are acting as predetermined breaking point in case of overload. The manufacturer Schartec cannot deliver spare parts, they proposed to try the drive trolley of a newer garage door opener version - but it also has a different belt drive assembly, in this case all parts would have to be replaced. I recreated the two damaged parts, printed them 100% filled out of PETG - since then my garage door opener is working perfectly with these parts. Should work for all Gen2 versions of the Schartec garage door openers - Prime 600, Prime 1000, Prime 1200, Prime 600 Speed, Prime 1000 Speed
