Ortlieb MicroTwo mounting adapter for Topeak Wishbone

cults3d

After mounting the new Topeak Wishbone on my gravel bike, I could no longer use my Ortlieb MicroTwo I use as an emergency tool bag, since both need adapters mounted to the saddle rails. Since the Ortlieb MicroTwo has a screw-on mounting plate, I designed this replacement mounting plate that acts as an adapter to the Topeak Wishbone mount. This allows me to keep the Wishbone's mount on my bike all the time, while also using my Ortlieb MicroTwo during normal use, and makes it easy to mount the Wishbone once I'm going on a bikepacking trip. In order to mount this part, you need a special wrench (https://www.thingiverse.com/thing:5524180) which I have designed as well to hold the internal nuts of the Ortlieb MicroTwo. I designed the part in Fusion360 with tolerances suitable for well tuned 3d printers. Although you can print it yourself, I only recommend to do that as a proof of concept, since the thin neck of the part may fail rather quickly when printed with common materials such as PLA, PETG, ABS or ASA. I recommend getting this part manufactured through a service that offers Nylon MJF printing, preferably with glass fibers for added strength. A cheap service you can use is JLCPCB's printing service, where I got mine printed for 16€ shipped.
