Leveling/measuring/comparing tool for 3D printer or other uses

thingiverse

I needed a way to compare one side of the z-axis level to the other side on my 3D printer as it sags when the steppers are shut off. I ordered parts to link the z-axis lead screws together, but in the meantime, this tool makes it easier to compare the two sides. **Marked "work in progress" because the bolt might need to be slightly smaller by about 0.1-0.2mm** or I printed the base with too much infill. Print with no more than 50% infill. For a screw that's too tight, apply some chapstick or other lubricant to the threads and work the bolt in and out. The problem might also be that one side of the bolt thread is exposed, so it distorts the threads on that side relative to the non-exposed parts. I used the a library that's technically very good however it looks like my $fn value was too high, thus producing a very large STL file. It also takes a very long time to render in OpenSCAD.
