After using @JoshK’s calculator and 4-cube form file, and from reading various ideas on the topic here, plus noodling a bit myself, I created a new excel calculator to insure dimensional accuracy in all three axes, as well as a step-gauge and test cube.
Dialing in your printer is really important if you’re prototyping injection molded parts that need to snap together, so that’s why I built this. I could get X & Y pretty good with Josh’s calculator, but my Z dimension was way off, and was causing problems.
Give it a whirl and let me know how it goes for you. After calibrating my printer with this, the 2cm cube model is literally within 10um in all 3 dimensions.
Calculator: (rename extension .obj to .xlsx. I had to change to upload it….)
