This print is a stand and blocks to show the infill rates of a slicer. If you don't like the percent I put on there 0 to 40 by 5, I have the Tinkercad link where you can copy and tinker the lettering to say the percent you want.

Print instructions

when printing the file named percent infill3 don't put supports on it. When the overhang on percent infill3 starts to print you cancel the print so it shows the infill.
