Bottle Cage for Bikes

Since there was no Bottle cage which could fit onto my bike yet, I had to design my own.

My frame tubes have a diameter of ~45mm. But it should also fit well onto bigger frames:

Bottle Size:

My bottles have a diameter of ~76mm (1L Coca Cola or Fanta bottles which I reuse as waterbottle). The cage should fit up to 80mm. But it also depends a bit on the size of the screw head you use to mount it.

The cage has a heigth of 150mm. This should support most bottle sizes and the bottles should stay inside by gravity. Some extra tall ones migth need extra securing, so they don't fall out.

Mounting:

The Mounting can be done with 2 screws:

There is also a 1mm gap on the back side of the screw holes. This is because some bike manufacturers use rivet nuts to insert the thread into the tube. And those rivets are a bit higher than the tube of the frame.

Printing:

I would recomend to not use “brittle” materials but something more elastic and impact resistant. Also the layer adhesion should be quite strong. PETG or some ASA/ABS Filaments are good for this. I used some old esun ABS (the newer Esun ABS has a different blend and is more brittle in my experience).

• Can be printed without support structures (but I will later also test a version with tree support)
• You will need quite some cooling to get the thinner parts nice
• 0,4 nozzle → min. 4 walls/perimeters  
• 0,6 nozzle → min.3 Walls/perimeters
• 30% infill or more (in most sections of the part it won't make any difference if you change this…)
• 3 top and bottom Layers
