"TolRolls" - 0.05 to 0.3mm clearance tests - 1 gram each :-)

thingiverse

First, if you are really looking to check your tolerances quickly, you might have a look at my "Tighty", that is, due to an indexing bug I assume, not searchable: https://www.thingiverse.com/thing:5707989 This is a 1 gram tolerance test "benchy" collection from 0.05mm (insane) to 0.3mm (too easy) to check if your printer can print in place mechanical parts without fusing them. Full features list: - Very tiny thus fast to print - No infill needed - 1 gram per test :-) - Elephant foot tolerant - Eyeglare to the tested clearance possible from a cut in the top - Screwdriver hole in bottom to unlock - Tested value printed on the side Warnings: - Good adhesion to the bed required General advices for a good printed parts tolerances on the printer: - avoid seams that add volume to the parts, that usually where the parts bind together. look for settings in your slicer to reduce extrusion at end of lines. - The faster te print, the worse the imprecision. If precision matter, print slowly. - Avoid elephant foots induced by compressed first layers (but the TolRoll is already taking itnto account) [Edit] I quickly replaced V1 with V2, the last one have a stronger top grip, the central cylinder sticks better to the plate. Look at the stls preview to see the small changes in the final look. I also added interval values: 0.075, 0.125 (close to typical tight clearance in imperial system: 0.005in>0.127mm) , and 0.175
