Back when I first designed the “version 2” of my pinball playfield inclination tool (version 1 was a simple wedge, allowing the user only to measure a single inclination), I didn’t yet have a 3D printer – I had to rely on a friend to print it for me.
Well, that’s changed now, and with that I was able to experiment a bit more on this tool to try to evolve it and solve the main complaint I have about it – it is annoying for it to be a two-piece tool, requiring the bubble level to be moved from step to step.
With that, I present version 3 of the tool, now with built-in bubble levels! It uses 10x10x29mm bubble levels that are cheaply available online. On the plus side, reading the tool is super quick and easy, and the tool now includes the ability to read side-to-side level in addition to inclination!
On the downside, I find these cheap bubble levels not super accurate, so some tweaking is needed to get it to read correctly. I’d recommend comparing the levels against v2 of my tool (see the post here), and try flipping the little bubble levels around if they don’t read the same. Anyway, I thought I’d post the model here in case anyone wants to give this one a try!
