I had a good experience 3D printing a pump holder for my bike and I wanted to share it since I couldn’t find anything similar when I started thinking about this project. Hopefully other folks might find this useful!
I have a 3T Exploro that I use for both road and gravel riding/racing. I’ve had a lot of issues with CO2s so I always have a minipump with me. It always annoyed me that I had my nice aeroish bike but had a minipump hanging off the side of my bottle holder. My Exploro has top tube mounts for bottle holders or bento boxes so I decided to try to use those mounts to hold the pump in place. I used onshape to design the pump and then had a friend with a 3D printer print it in PETG. The pump design is here: Onshape.
I used large washers to better distribute the load from the bolts. I used two sided velcro I had around the house to hold the pump on the mount. So far the mount has worked really well! I did a very wet and muddy gravel race a few weeks ago plus plenty of road rides. No issues with vibrating or anything like that.
