About this 3D model

I reworked this model from another model i found on thingiverse (http://www.thingiverse.com/thing:190146) It appeared that i had to move a little bit the fixing holes so that i can fit this part without forcing on the part. I also enlarged a little bit the pneufit hole so that it's a little bit easier to fit inside. You might require to force a little bit though as you want your pneufit connector to stay put. This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/7mwkRvWQS9S
