Real Grade RG Gunpla/Gundam action base adaptor

found this awesome HG Gundam stand on thingiverse https://www.thingiverse.com/thing:2702736 and was dissapointed it didnt work on my RG gunpla due to a different mounting design. made this in onshape, the circular end goes into the stand and the square end goes into the Gundam. It fits somewhat loose so you can lift the Gundam off, but it shouldn't fall off on its own
