Spacer for 20x20 stacks with M3 screws

cults3d

Edit : Uploaded V2 with slightly bigger holes for the screw and a tiny bit thicker spacers for better printing (spacer is exactly 0.8mm thick, which is perfect for a 0.4mm printing nozzle) Just a simple spacer to space boards on a stack (like between ESC and Flight controller). This spacer is 4.5 mm height, has a 3.5 mm hole for M3 screws but is small enough (5.1mm external diameter) to fit on 20x20 stacks. Obviously, it will also fit on a 30x30 stack. Best printed in hard plastic like PLA (haven't tried in TPU...)
