Horizontal Expansion Calibration Shapes

thingiverse

Tool for calibrating the "Horizontal Expansion" setting of your slicing profile. Instructions: - Slice and print the 2 STL shapes - Clean the resulting parts from any blobs and burrs - Determine where is the larger base and the narrow one for both parts (they have a slight angle on their profile, like a truncated pyramid shape). - Insert the solid shape into the hollow one, entering the narrower tip of the first one into the larger base of the second. - Push it in until it would not go in any more, applying some good pressure. Now, a few cases are possible: - If the solid shape perfectly fills the hole of the hollow one: Do not change your Horizontal Expansion setting, it is perfect! - If the solid shape goes completely through the hole of the hollow one, increment your Horizontal Expansion setting by 0.2mm and do the whole procedure again. - If the solid shape would not enter the hole of the hollow one at all, decrement your Horizontal Expansion setting by 0.2mm and do the whole procedure again. - Otherwise, take a caliper and measure the total height of the two bonded parts in milimeters: The value to add or substract is (Total Height - 10mm) / 50. - If the solid shape does not fully go into the hollow one: Substract the Value to your Horizontal Expansion setting. - If the solid shape goes in past the top of the hollow one: Add the Value to your Horizontal Expansion setting.
