Or maybe you have an idea to make it work on a mountain bike too? Even with extra clamp force I think bottles would shake out if you just ran it on your downtube, but I figured it was still worth sharing.
The design really only works holding your cans vertically, so it’s mostly for putting on your town bike’s bars. I settled on 2.25mm walls, so 5x passes of the nozzle printing a little 0.45mm snausage of plastic. What that means is my wall thickness needed to use multiples of 0.45mm to make it print cleanly rather than struggling to fill gaps. You can adjust this in your slicing programs, but I don’t think any slicers adjust it dynamically during your prints. In the XY axes the nozzle I use is 0.4mm wide, which, after a bunch of frustration on my part, turns out prints 0.45mm lines of filament. I generally use an unnecessarily low 0.1mm layer height so it builds up from the build plate (Z-axis) very slowly, but the finish looks nice and smooth. The hardest part was dialling in the design for printing efficiently. Now it’s solid enough that I think I will run it without any retention on my gravel and XC bikes, but I gave it an option to run a bombproof Voilé Nano strap as well. 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.
#WINGS 3D SNAP FREE#
Wings 3D is open source and completely free for use in both personal and commercial projects.My role at Pinkbike/Outside is mostly spreadsheets, meetings, cat-herding Levy, and the occasional salty comment. This is the data structure used to store the adjacency relationships between edges, faces, and vertices in a Wings 3D model. Wings 3D gets its name from the Winged Edge Data Structure (WEDS).
Wings 3D is written in Erlang, an open source, functional programming language distributed by Ericsson. There is no support in Wings for animation. Wings 3D offers a wide range of modeling tools, a customizable interface, support for lights and materials, and a built-in AutoUV mapping facility.
Wings 3D is currently maintained by Dan with the help of the great community. Richard Jones (optigon) maintained Wings and coded many new features between 20. Originally inspired by Nendo and Mirai from Izware, Wings 3D has been developed since 2001, when Björn Gustavsson (bjorng) and Dan Gudmundsson (dgud) first started the project. Wings 3D is an advanced subdivision modeler that is both powerful and easy to use.
