Gridfinity Edge Finder Holders

These are two Gridfinity holders that I designed to hold the edge finders I use with my milling machine.  One of them holds two Starrett edge finders, models 827A (3/8") and 827MA (10mm).  The other holds a set of four Fowler edge finders, kit number 52-575-100-0.

Like my other Gridfinity models, the bases are altered to accept 6x3 magnets as a press fit, with the upper surface of the magnet holes modified to make the slicer bridge across correctly for a clean result.  I usually print Gridfinity models with a 0.6mm nozzle and 0.3mm layer height, but it should be noted that these features (and especially the text on the one unit) will print better with a 0.4mm nozzle and 0.2mm layer height.  The silver holder was printed in Prusament PLA using a 0.4mm nozzle, and the blue ones in Overture PLA using a 0.6mm nozzle, all on Bear upgraded Mk3S+ printers.
