If you have to make them I would suggest starting with a high grade flat head screw and modifying it with a bonded on collar and the head turned on a lathe to reduce its diameter as needed.
Brownells Oxpho Blue is an excellent cold blue for tooling and easy to apply to the bare parts as needed.
Loctite makes a glue for vinyl, plastic and fabric that works very well on both vinyl and bondable plastics. It is available in most hardware stores.
For the living hinges I would suggest cutting away the part at the case junction and then bonding/screwing on some of those tiny box hinges they...
Also important to have signed releases that they recognize the risks.
IMO makerspaces serve an important function in a time when traditional manual arts have been declining for decades. I wish you success.
Bears are incredibly strong. I've heard them described as a sensitive nose attached to a huge appetite, equipped with all the tools needed to obtain food.
I've seen photos of vehicles where they had hooked their claws into the top of a door and then folded the window section down like it was...

My go-to for softening old grease is Marvel air tool oil.
After it soaks in a while I wipe off as much as I can and then apply new grease. It may take multiple applications to remove the old crud. If this is a high load application I would suggest using an EP (extreme pressure) lube such as CMD...
I agree with Billtodd.
My guess would be that the coaxial plug connects to a wall wart with Bluetooth activated bidirectional on/off to operate window blinds in a difficult location.
I agree 100%.
