Stromer ST1x bike trailer adapter plate for Weber hitch

Stromer E-Bike needs an adapter plate for mounting a trailer hitch near back axle. The optionally buyable original ST1x adapter fits Thule chariot hitch but not Weber hitches. For a Weber-Product hitch a 45 degrees setup is required. I asked Weber for a mount solution on ST1x, they answered that at the time (november 17) there is no way to connect a Weber hitch on Stromer ST1x bike. So I designed my own.

I've made some designs to connect a Weber hitch on Stromer St1x. You can print this part
