@ascentale @iris @bikenite A2: Bike trailer! :D
i didn't build the frame, that was adapted from a kid carrier. But I did build everything else!
Also the trailer hitch on my bike so I could hook my trailers up. That I did build entirely from scratch, from design all the way up to working implementation.
Hm, what else.
My in-triangle cargo wedge.
I reverse-engineered the accessory mounting system that had no accessories available here for stupid IP reasons and built my own attachment mechanisms so I could have interchangable cargo basket/containers over the back wheel.
I built a handheld radio holder for my handlebars, so I could ride around and do FRS and/or shortwave. (Mostly FRS, the shortwave is kinda big and heavy.)
