Gap Tester

thingiverse

This is my own design, but it's heavily inspired by the MMuse tester remix:\r\nhttps://www.thingiverse.com/thing:2357531\r\n\r\nI printed the above tolerance tester on April 5, 2019. Then I noticed that I could free everything from 0.5 to 0.15 millimeters but not the 0.10 mm.\r\n\r\nIt got me thinking: "Where is the limit of my printer?"\r\n\r\nSo I made this. It has solid straight cylinders, so you can take them out and check the dimensions inside and outside. If they're free, that's great. Steps are 0.15 millimeters, 0.14 millimeters, 0.13 millimeters, 0.12 millimeters, 0.11 millimeters, 0.10 millimeters, and 0.09 millimeters.\r\n\r\nAs you can see, the slicer does not even recognize the 0.09 millimeter cylinder at all. So that's a software issue, not a model or printer issue. The 0.09 millimeter will be solid, but the rest will work as expected. I really needed to use some force with the 0.10 millimeter cylinder, but it was eventually free. There were little or no problems with the others.\r\n\r\nAll the holes are 20 millimeters in diameter and the numbered cylinders are smaller, as shown in the dimensions picture. The object height is 16 millimeters. You need to print numbers to the bed side and hex holes up. No supports or raft are needed.\r\n\r\nThe STL file was exported with a 0.01 millimeter deviation, so the model is very accurate but also a big file at 200 megabytes.\r\n\r\nI made a slight chamfer for the edges on the hex 6 keyholes, just in case. If you use 10-20% infill, turn carefully. More solid or harder material could help. My test was done with PLA.\r\n\r\nCan anyone comment why the slicer (Prusa PE 1.41.3) won't do below 0.10 millimeters?
