I traced the Micro Swiss linear rail bracket from a photo after performing perspective correction on it, and it should be the correct measurements to make this work.
The MS Linear Rail kit is quite a bit wider than the roller kit, or stock bracket, so I don't think the original Manta MK2 base would fit securely as it would only be mounted with one screw. This uses one of the unused holes in the linear rail bracket.
The author remixed this model.
