About this 3D model

This is a Mini Nitrous bottle. I used a stubbie holder (aussie slang for drink holder) I model everything in my Architectural software called ArchiCAD which I have been using for the past 20 years at least. Maybe make the knobs 102% so they fit better, miner were a bit tight to fit. hope to see your remote control car, scooter, real car with one of these. please post photos
