This is a 3d printable file for the MakeSmith CNC gear stack assembly which would otherwise be made of 3 pieces of acrylic glued together. The "Gear Stack" file represents the part as visioned by the MakeSmith team. I was ask to make the part with a hole slightly smaller than 1/4" so I present to you the following parts. The "Gear Stack 7_32 hole" file represents the part with a 7/32" hole instead of a space for a 1/4-20 nut. The "Gear Stack 15_64 hole" file represents the part with a 15/64" hole instead of a space for a 1/4-20 nut. I recommend printing it with support turned on and about 30% infill with 3 layer walls. Insert a 1/4-20 nut into provided slot and super glue into place.
