As seen in my latest YouTube video, presenting a new technique for measuring pinball playfield inclination. This tool, which you can 3D-print yourself, allows you to get inclination measurements for a variety of different playfield slopes using an off the shelf bubble level. I’ll link the downloadable 3D model and acrylic bubble level it is designed for below, and you can see it in action in my video (also below).
I recommend using a label maker to label the different steps on the tool. The angles, from the highest step to the lowest, are:
- 6.5
- 6.7
- 6.9
- 7.1
- 7.3
In addition to the sizes above, you can effectively read the in-between even-numbered decimals by measuring an equal left and right deflection of the bubble on two adjacent steps!
Download the 3D model you can print yourself at home here: Wedge V2 STL
It is designed for the 95x40x15mm acrylic bubble level shown in the photo, you can buy it here.
And for a live demonstration of different ways of leveling your game, including using this tool, watch my video! Hope this helps!

I do not have a 3D printer to make a Wedge V2. Is there somewhere I can purchase one?
Hi Mitch! Unfortunately I don’t have a 3D printer, and had to have a friend print one for me, so it’s not something I can sell (hence giving away the 3D model for free). I’d recommend looking around where you live, I’ve heard some local libraries have 3D printers for instance. Or find a maker center. Try searching the web for “3D printing (your city name)”. Otherwise, there are online 3D printing services such as Shapeways who can print this for you, but I’m guessing it wouldn’t be cheap. Good luck!
