I've been printing a bunch too with a smaller UP 3d printer (4.5" sq print area). Here are a few of the things I've made. Most are car related because thats what I like to tinker on.
These are molds for 2 part urethane to make intake insulators for cars.
These are shifter shaft bushings for my daily driver. The current ones are worn out and discontinued...
Here is a quick and dirty gauge pod I made for my daily driver as well.
This is a mass airflow sensor housing for a 2014+ Mitsubishi Mirage. The stock one is integrated into the filter housing. You can use this for a custom intake.
It really is a ton of fun to play around with this thing.
