This tester tests a printers tolerance (required gap between parts so they fit and don't fuse) in both X/Y orientation, and Z orientation, and tests both orientations with print in place and assembly.

Print In Place VS Assembled Prints

As you'll see when testing with this print, if you print in place (parts printed close together at the same time on the bed), your printer will have less tolerance than if parts are printed separately then slotted together after printing. With print in place, if too close, they can end up fusing during printing. This test allows you to test your tolerance for both P.I.P. and assembled parts.

Dimensions and description of tolerance:

• All vertical X/Y testing poles (both assembly and print in place) are 10mm diameter.
• The holes for them have a diameter of 10.1mm - 10.35mm, meaning if the 10mm poles are centered within them, there will be a gap of 0.05mm - 0.175mm between each side of the pole and the inner wall of the hole
• All horizontal (z layer) testing poles (both assembly and print in place) are 5mm diameter.
• The holes for them have a diameter of 5.1mm - 5.35mm, meaning if the 5mm poles are centered within them, there will be a gap of 0.05mm - 0.175mm between each side of the pole and the inner wall of the hole

Post printing

You may find after printing that some of the print in place parts have very slightly fused but you can push them clear and then you can freely move them to see what your tolerance is, where as some will have completely fused and are beyond your printers tolerance with these print settings.

To test the tolerance of your printer with parts which are assembled post-printing, use the two separate testing poles on the empty holes.

Print Settings

I have inclued a profile which will print this tolerance test as shown in the photos.
However, to accurately test the tolerance your printer will have when printing something specific you'd like to print, you should print this tester with the same settings that you'd be using when printing the thing you're testing it for, so please feel free to tweak the settings to meet the layer height, extrusion width, temperatures, etc that you'll be using for the prints where you'll be applying the results of this test.

Parts printing solid?

The print in place (P.I.P.) parts for 0.1mm and 0.15mm will not just fuse in print, but will actually slice as part of the main body of the tester when sliced using the included profile.
That is by design. The tolerance of these parts is too small for standard print settings and won't be pritned as separate parts with such a small gap. However, with the right printer setup, the right nozzle size, and the slicer settings to match, these sizes can be used so are included for reference where needed.
