Ultimaker 2 and 3 tension indicator

somehow the original part that holds the tension of the extruder module of the UltiMaker broke off at the indicator pin. This pin is there for another reason: to hold the nut in place so it doesn't pivot.

I designed a replacement part that's as close to the original as possible with SolidWorks. You can print it in PLA because it does not get under a lot of stress when it's in use. I printed it in ColorFabb PLA/PHA sky blue.
