Helio Spring Mini 30x30 adapter board

The board is ment to be attached with screws to the 30x30 stack. There is a room for helio usb port so it is possible to mount it directly to it. There should not be any nuts needed as the holes are tight (TEST THAT!). Every printer is different so test this before flight. (if mounted without nuts, you take whole responsibiltiy for any damage done in case of failure)
