I made a bunch these up today on the cnc and I figured it would be a good idea to show them here because they were real quick to make from some scrap
should anyone want to do a run of these for themselves or we want some for the shop, I left a copy of the v carve file for the fancier ones on the desktop of the swift
they are 12" with a pair of 1.5" holes, and a bigger 3.5x2" cutout in the center, giving you all kinds of clamping options
