Update 2 Aug 18: I was notified by a user that my previous post for this part was no longer available. As a result, I have reuploaded the files here.
Allows you to stack bottle/cargo cages side by side.

There's a machined & 3D printed version available. The STL is only for 3D printing. Plus an assembly for visualization purposes.
Just checking there, it doesn't look like the bottle cages should interfere with one another. I tested with the machined version, which is tighter; the 3D printed version should have more room.
The 3D printed version requires:
- 3 M5 x 0.8 bolts: 1 for securing to the frame, & 1 per side/bottle cage
- 2 M5 x 0.8 locknuts: 8 mm width, 5 mm height
Dimensions were guessed using the uploaded reference image from Bikepacking.com
3D printed version is about 5 mm taller to account for the height of the locknuts. The machined version would be threaded & therefore not require the locknuts.
I assumed a nominal diameter of 3.93 mm for the M4 bolt in the picture for scaling everything.
