A mountain bike bottom bracket cable guide for 1x drivetrains. Since it is common to do resto-mods on 90's mountain bikes by converting them to 1x drivetrains, I thought it was silly to use a double line guide on the bottom bracket shell. Since my was broken anyway, I came up with this part instead. You will go faster since you probably save 3 grams!

I recommend printing with 100% infill using PETG (I used PETG-CF in the version shown in the pictures). Print it standing up on the long flat edge for best bed adhesion. I used supports in PLA on a multi-color machine, You might be able to print with no supports though.
