Dual Nightwatch Extruder: BOM Fasteners are the wrong length. #69
Description
There is, what I think, is a mistake in the BOM and CAD file regarding the 10x M3x25 BHSC machine screws. The CAD file shows the length of the shanks of the screws to be 22mm. 22mm is actually too short for the four screws below the motors that join the mid body to the cover, so those should be M3x25, however M3x25 is too long for the two other joints where the screws sit under the gears. I discovered this while trying to assemble the parts to see that the screw wouldn't tighten down all the way without punching out of the back of the cover. M3x22 is the right length for that.
There seems to be enough relief for the remaining joints used to secure the motor plates to use M3x25, but 22mm provides enough length for full engagement of the insert.
