Hinge for (new) multiboard

This is a hinge compatible with multiboard. It can rotate 180 degrees (-90, +90) from flat. I have another variation of a hinge that can attach to any place in the board: https://makerworld.com/en/models/1263744-hinge-for-multiboard This model is not a derivative work of the multiboard files and thus is not under the Multiboards license.
