Thule Chariot hitch to Croozer Cargo/XLC Carry Van adapter

thingiverse

I own an old Croozer Cargo bike that's now called the XLC Carry Van (https://www.xlc-parts.com/road/accessories/luggage-transporter/1659/fahrradanhanger-carry-van-bs-l03), because the new Croozer Cargo has a completely different design. I didn't like the hitch on my original bike, so I replaced it with a Weber hitch. To attach the Weber hitch, I had to cut off the original part on the drawbar and drill a hole into it. This worked well for quite some time. A few months ago, my wife and I bought a Thule Chariot Cross child trailer. Thule has its own hitch system with a ball head that's also a nice design, but it's completely incompatible with the Weber hitch. So, I looked around online and found out that you can buy the ball head and locking pin assembly as spare parts. I ordered these parts, thinking about the corona virus crisis at the time (just in case someone reads this in a few years). Every seller online was flooded with orders, and delivery companies were overwhelmed with shipping boxes. So, it took almost two weeks for my parts to arrive. I got impatient and thought, "If I own a 3D printer, why not just print an adapter, but also the missing parts directly?" So, I designed a ball head that you can see in the picture and the flexible part for the locking pin after measuring the original parts using Fusion 360. To use the printed part, you'll need to have the original locking pin. I printed the ball head with TPU, using 2 mm perimeters and 2 mm bottom and top layers of PETG. I took a short test drive with a heavily loaded trailer and it didn't break, but for safety reasons, I don't recommend using it. After my ordered parts arrived, I used my printed adapter sleeve and the original parts from Thule.
