the Controller is designed to be printed standing up without supports. There is a bit of postprocessing required to remove the custom supports for the Trigger button flexure.
Turned out great. I printed four at the same time and all four were complete. Printing with a brim would be a recommendation (I didn't and had to apply some glue to one controller midway through the print).
Printed it as a last resort because one of my daughters games requires the single controller on its side and me and my wife hate not having something bigger to hold. This worked great after I printed mine she asked for one lol
