Mavic UST Bladed Spoke Wrench (Parametric Design)

thingiverse

This is a pair of plastic knobs for truing Mavic UST bicycle rims with a 6-spline 5.65mm nipple and 1mm bladed spoke, such as (my) Ksyrium Elites. The object is built parametrically so you can tweak it to fit with your printer, materials, and rim type (since we all know how many bike standards there are to fit - I mean FFS, they had to make it a spline instead of the typical square ones). The spoke blade tool is totally serviceable tool. The wrench tool... Seems good enough to work in a pinch, but I'm probably going to get a [Park Tool SW13](https://www.parktool.com/product/double-ended-spoke-wrench-mavic-6-spline-sw-13) for my homeshop, since after just a few adjustments, this printed one is getting pretty gnarly. On the bright side, since it's printed, you can chuck one of these in each of you bike bags, and it'll cost (and weigh) basically nothing. I printed mine using PETG on fine settings, with a 0.5mm nozzle, 4 wall layers and 33% infill. You might have to tweak the dimensions of for this script and run them again to get something that works with your printer. You pretty much need to get as tight of a fit as possible to not have it strip out immediately. In fact, heating the wrench up with a lighter, then smushing it onto a spoke nipple seemed to be the best way to get a snug fit. I'm definitely open to suggestions on how to make this one better/more durable. This object was parametrically designed using Python, FreeCAD, and CadQuery, so the [code and yet more documentation is available here](https://github.com/swolebro/caddyshack). [Here's a perma-link to the code that made these files specifically](https://github.com/swolebro/caddyshack/tree/4d5234025cbe39bd4361d73183bcb2e942d27887/scripts/bikes). There may have been updates/improvements/reorganizing done since then, however, so I suggest you take a look at the latest revisions too. Pretty much any design on the git project should be on my Thingiverse profile as well. Some (but not all) of my designs also have videos to go with them, which I am assembling into a [YouTube playlist here](https://www.youtube.com/playlist?list=PL9xPdBFt5g3QmsrRzn3PynVNeJ7LHVtZS).
