About this 3D model

I was inspired by this GREAT thing http://www.thingiverse.com/thing:257089 because I needed the Z axis mounts and I wanted them to all match. I like my kit assemblies to look clean and uncluttered as possible. ;=}The upper Z axis mount probably could use some improvements so it could fit on the front center M3 screw hole instead of the side one like I have it. Also the upper Z axis mount is hard to screw on because of the position. I spent enough time messing with it for my tastes and it works. The lower Z Axis mount uses 5mm X 15mm screws (I tapped both ends of my Z axis rail :=} ). My screws are a bit long. It was all I had available at the moment. UPDATEhttp://youtu.be/6VvwGszE8Xo This video shows that the stock version of Shapeoko 2 does TECHNICALLY function as advertised. However, it's very unreliable and can be downright dangerous. I had to go through 2 of those 1/4" thick sheets to get the small bracket above to cut properly. It's unreliable behavior wastes time and money on materials. That's what Inventables counts on, money from people having to buy materials. I have since discontinued using the machine until I obtain a TinyG stepper motor controller. The GRBLShield is poorly designed and allows way too much electrical noise to be generated which has caused my Shapeoko 2 to plunge unexpectedly into the waste board and actually breaking my fine engraving bits. This has happened twice when I invoked the Homing Command. The hard limits option doesn't work because of all the electrical interference so there's no protection. If you have to have a Shapeoko, buy the mechanical kit, NEMA 23 motors and TinyG. The full kit has faulty electronics and small motors. Who needs a glorified "Spyrograph" ?
