Update 2023: Bought an MT8 and added a fitting for it here.

---

You want to customize your Magura MT5/MT7/MT8/MT Trail Calipers without spending a fortune on those expensive plastic rings? Look no further, this model has you covered.

They're exactly the same size as the originals ones with the exception that they are modeled solid. Looks best when printed with a glas or PEI sheet so the surface gets really shiny.

I printed them in PLA with 100% infill. They fit tightly, if your printer is not perfectly precise you might have to scale it down. With PLA they tend to break when you try to remove them but then again this part is dirt cheap and you don't need to remove it for any maintenance tasks anyway. I have no long term experience with heat on the brakes so it is possible that it gets pretty hot and PLA could get soft.

Print instructions

Recomended with 100% Infill and a rather big layer height like 0.2 since only the top layer will be visible.

You can print in any material you want. I used Das Filament PLA Tom's Infinity Blue in the example foto.
