I’m sure the engineers here are rolling their eyes at this, but the breakthrough for me was understanding that “everything is a spring.” Once I made the holder elliptical rather than round, it held the pump firmly and wasn’t too hard to get into. If I made it too tight or wrap too far around, it was hard to get into and the pump still spun in the holder-while if I made it looser or with less wrap, it popped out too easily. Initially, I struggled to make my design actually hold the pump firmly. A long time ago I did a design that was similar to the excellent Jank Components one, but wanted something a little more minimal and with two sides further apart for more stability. I don’t know why, but mounts that stick out off the side of my bike bother me for no good reason.

We wanted a light, low profile pump holder that would sit in-line with the frame. I started working on this OneUp pump mount for a frame builder who’s doing a very cool build for her entry to a handmade show later this year. Let me know below what you think I could improve with these designs, or what you think needs to get made!

I've included STL files for a few of the designs below so anyone with a 3D printer can pull down the file and try printing them. I thought it’d be interesting to highlight a few things I’ve been messing around with, and hopefully encourage you to get out and make your own stuff. I’m constantly blown away at how easy it is for someone with zero engineering experience to think of something, model it on a computer, press a button, and then it just… exists? Through my very slow learning process I’ve made spacers, pedals, pump mounts, cable guides, bottle cages, and more. Additive manufacturing on an industrial scale has huge potential for brands like Atherton Bikes (check out our podcast with them for more additive nerding), but I’ve been even more interested in the accessories and gadget-level stuff.

But every winter I try to learn something, and in 2021 I got a MatterHackers Pulse XE and spent a bit of time learning about 3D printing. My role at Pinkbike/Outside is mostly spreadsheets, meetings, cat-herding Levy, and the occasional salty comment.
