Needed roof top mounted A/C for my N scale tour buses so I made this up real quick in Tinkercad. Might work good on vans, trucks, ambulances, food trucks, ect.
Needs to be scaled down. I found 20% to 22% scaled down worked good on N scale depending on the bus.
For HO, you'll probably be in the 40% to 50% range but you'll have to find a size that works for you.
Printed at 22% on my Anycubic M3 resin printer and it only took about 10 mins.
This is my first upload on here. I hope someone finds it helpful. Feel free to use it how ever you like. Please share a photo if you do end up using this on your own project.
