Our SKADIS installation required a standoff with an additional ¾" of height so I whacked this together. You can adjust the height by modifying the AdditionalHeight user parameter in the attached Fusion project file (setting AdditionalHeight to 0 will give you the standard 20mm height).
Print upright. A brim is probably a good idea (I've had mixed results printing without).
