thingiverse

Allows you to stack bottle or cargo cages side by side. http://www.bikepacking.com/gear/wolf-tooth-b-rad/ Bikepacking review. https://www.wolftoothcomponents.com/products/b-rad-double-bottle-cage-adapter Wolf Tooth page for this product. There's a machined and 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 three M5 x 0.8 bolts: one for securing to the frame and one per side/bottle cage. Two M5 x 0.8 locknuts are also needed: eight mm width and five mm height. Dimensions were guessed using the uploaded reference image from Bikepacking.com. The 3D printed version is about five mm taller to account for the height of the locknuts. The machined version would be threaded, therefore not requiring the locknuts. I assumed a nominal diameter of 3.93 mm for the M4 bolt in the picture for scaling everything. https://www.bmwclassicmotorcycles.com/parts/categorie-3/nieuws-4/ This chart was referenced. https://grabcad.com/library/bicycle-bottle-cage-1 Mohammed AlMahasnah's bottle cage model on GrabCAD was checked for interference.
