Tolerance & Clearance Test Board

thingiverse

If you're designing for 3D Printing or you have a new printer, this tolerance tester will not only give you examples of the tolerances of your printer, but allow you to get a feel for how tight or loose you want to design your clearances for various purposes. An 8mm Plunger is Printed and holes 8.0 - 12.0mm are relieved in a 2x1 Gridfinity Block. You can put the plunger in each of the holes to see how tightly your printer prints the actual dimensions as well as get a feel for the various clearances. Clearances: 0 - 1mm (0.1mm Increments) 1 - 4mm (0.5mm Increments) If you want to get the feel for an unprinted object as well, this was designed for an 8mm rod--I used a <a href="https://www.amazon.com/CRAFTSMAN-Extension-Bar-3-Inch-CMMT43539/dp/B07QH88676?crid=U60XXPSS20TD&keywords=craftsman+43539&qid=1676992865&sprefix=craftsman+43539,aps,105&sr=8-2&linkCode=sl1&tag=themodernfrontier-20&linkId=8dea3bec2adbb775964d7a1f20a7578d&language=en_US&ref_=as_li_ss_tl">Craftsman 1/4" Socket Drive Extension (CMT43539)</a> which measured to 8mm on calipers for the main rod section.
