After I upgraded my breaks to the current deore generation, I couldn't reach my shifting levers due to the changed clamp position. 

This extension extends the lever by about 18mm. Installation is a bit fiddly, but once in place, it should click in place without any glue. Therefore it can also be removed without any problems.

Note: This model was made for the old generation altus SL-M370 and probably won't fit the current SL-M2000 version. But feel free to test and leave a comment if it worked ;)

I printed this in original orientation with full supports. Organic supports worked best for me.

Print in a UV-resistant material like PETG or ASA. PLA or ABS likely won't last long.
