About this 3D model

I NEVER HAVE TO LEVEL MY BED AGAIN!!! costs less than $8 and takes less than 20 min to 3d print. This is my take on an auto level mount and arm for the Prusa i3x from DIYTechShop. I used a single TowerPro SG90 9G servo (2 pack from amazon is $8) found at:http://www.amazon.com/gp/product/B008Q6Z36Q/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1 and the stock end stops (Honeywell). I do recommend upgrading to a better micro switch eventually. in action:https://www.youtube.com/watch?v=Y6XA-D2Zx2Yhttps://www.youtube.com/watch?v=1XyhIbW0TQk hooking it up is actually pretty easy refer to the makerfarm tutorial :https://www.youtube.com/watch?v=awsI9bMndJA ***this design should work with other DIYTechShop printers.
