Description
The screw and case for it for a RC plane bungee launch system. Screw is printed in halves, horizontally, then alu tube 8mm in dia is placed inside for strength and then the halves are glued together with epoxy and/or CA. Case is printed vertically.
I used 10m 8mm bungee cord like this: https://aliexpress.ru/item/1005001894111448.html
It is connected to screw with optional carabiner clip and I attach after screwing into ground: https://aliexpress.ru/item/32983302862.html
Then 5m kevlar kite cord goes and the keychain ring to connect to airplane hook.
In test the bungee was extended with tension 10kg (it is not a limit, I suppose).
