Teeny Calibration Thingie

thingiverse

My ADHD-riddled brain hates tuning and calibration prints that take forever, so I made this little cube thing to test out the main parameters and give me a good head start tuning new filaments and other printer params. I use printing for mainly engineering prints so absolute perfection is not my goal, mainly dimensional accuracy and decent top/bottom surfaces for clean assemblies. Designed for 0.4mm nozzle and 0.2 layer height. Far from perfect and requires some "eh, it'll do" mentality. But works fine for me and take less than 10 mins to print on most printers (5-6 mins on my Ender 5 S1 at 200mms) Pro-Tip: Orientate the small cube to top right on slicer so you can quickly identify X/Y axis when it's off the bed. Features: -20x20x1mm base -10x10x10 Cube -5x5x5 cube shelled with 0.8mm walls (2 x lines with 0.4mm nozzle). Handy measurements you can take: -Dimensions of 5mm and 10mm Cube for esteps calibration -Wall thickness of 5mm cube shell for flow calibration -Check height of 10mm and 5mm cubes VS 1mm base, if the base is shorter then you are squishing the first layer. (10mm cube vs 0.9mm base would mean 0.1mm of first layer squish you can adjust form the Z offset to get perfect first layer.) -(Visual) Flat surfaces can be used to visually tune top/bottom flow rate between prints if top surface is a bit ragged.
