Carisma GT24 Servo Steering Link

Steering Servo Link for Carisma 1/24 scale GT24 RC Car. I brokme mine on the first day. I tried a design from someone else here http://www.thingiverse.com/thing:2418662 but I couldn't get the holes in the part for the screws. I don't know how to edit STL files so I designed my own using Autodesk Fusion 360 with measurements taken from the original broken part. This was as close as I could get, I don't have much experience creating things. I also sanded down the bottom smooth so it would slide
