Hello friends,
I am at my wit’s end. I need one of the two counterbalance gearboxes driven by the motor for my electric conservatory awning with counter-tension system and chain. (This brown part in my hand with the broken plastic gear inside).
>Unfortunately, I don’t know the brand of this part. I would be very grateful if you could help me—maybe someone knows where I can get something like this or who the manufacturer is/was. (It’s not the newest system anymore)
Thank you very much for your help! Best regards, Peter

Here are some more unusual ideas: try searching for local repair cafés, repair bars, electronics advice sessions, repair meetups, electronics hospitals, or "Café Kaputt" where enthusiastic hobbyists might help or have new ideas. They could provide assistance ;-)
- On the motor’s nameplate, I saw the company Dunkermotoren mentioned; they manufacture blind actuators (motors too), so they might have made this assembly or know which manufacturer produced it back then. It’s a slim chance, but it doesn’t hurt to ask.
- From this point, it could get more expensive: by searching for “3D printed spare parts,” you can find information about producing replacement parts using a 3D scanner and 3D printer. This is a feasible alternative. The color of the gear suggests it is made from polyamide (commonly known as nylon). It is surely a highly loaded component. I can’t say how well this material can be printed. There is also selective laser sintering—whether this is suitable and affordable is the next, and usually more important, question.
If pursued, the part would be scanned with a 3D laser scanner, missing areas would be reconstructed, and then the data passed to the printer. These are processes already considered or used by aircraft manufacturers and medical product makers. Near us, there is the company SLM Solutions Group AG, working with metal powder. But this is just a general suggestion; ultimately, it must remain affordable. They operate at a higher level.
Please do not expect that this inconspicuous part, which probably cost only a few cents in the original serial production, will be available at a similar price. A replacement part could quickly reach the 100-euro (about 100 USD) range. You will have to decide if repairing it is still worthwhile or if converting to a different drive system is possible.
