I printed and used the slim version without problems and later remixed the slim design with the Hero v2s replacement Hot-End mod for CR-10/Ender 3 style hotends (see: https://www.thingiverse.com/thing:3036933). What gave me slight problems was the lower screw of the servo was splitting at the layer bound. Nothing a drop of superglue couldn't fix though.
