About this 3D model

This is a standard 57mm automotive gauge pod / hole filler. I decided that this would be use full for all the DIY Car guys out there. I noticed I can pick up a voltage meter off of ebay for like 1.25 and I can print this and cut (or print with the hole already) a hole out for the voltage meter. This is my first 3d model, and it did successfully print. if you have any questions please let me know. Also for some reason when i load this into cura i have to scale it... if you can help me pop me a PM Figured it out. the Volt gauge has the proper size no need to scale!
