Mini Clearance/Tolerance Test

thingiverse

A remix/remake of tolerance test by druppy. https://www.thingiverse.com/thing:1420023 I resued the numbers and basic idea, but remade the rest from scratch. This is a clearance/tolerance test for FDM printers. I removed half of the pegs from the original as a 0.3mm - 0.4mm clearance is ideal for most FDM printers, and if yours can handle 0.4mm then it should be able to handle anything above that. If not then you definitely need to calibrate and tune it. I also made it smaller and thinner to reduce print time and filament usage. This should print in roughly 40 minutes or so at 25% infill, tho it will depend on your slicer settings. Just see if the pegs (well buttons now) can pop out of the holes after the print completes. Each button is 10mm wide and has additional clearance marked after the button marked equal "=" The equal button should NOT pop out. It is a baseline The 0.3 and 0.4mm ones should pop out, and at the very least the 0.4mm one should. Calibrate your esteps and tune your printer/settings if it does not. I doubt the 0.1mm and 0.2mm buttons will pop out, they're just there for additional comparison. I don't know of any FDM printers with that resolution, but it might be helpful for testing smaller nozzles. This was primarily made for 0.4mm nozzles which are pretty standard. The overall dimensions are: Buttons are 10mm wide x 2.48mm tall. Plate is 86.4mm long x 23.9mm wide x 2.7mm tall (that's including the numbers. it is 1.97mm tall without them) I have also included the base MQO files I used to make this with, in case anyone wants to modify or improve this design. Be warned it's a bit messy and disorganized, and I apologize for that, but it does have all the hole and button guides as well as all the number markings. You will need an MQO importer to open it, and one is available for Blender. Enjoy!!!
