About this 3D model
This is a simple keyboard tray that mounts to a 2020 extrusion. It was designed specifically to hold this Rii K12 Ultra Slim Wireless Keyboard/touchpad: http://amzn.to/2ghaDOl It can of course hold other keyboards or items. I use this in conjunction with my 7 inch Raspberry Pi Touch screen and Pi 2 to run Octoprint. It provides a nice little kiosk on the printer itself. The 7 in LCD mount can be found here: http://www.thingiverse.com/thing:1670214 The 7 in Touchscreen can be purchased here: http://amzn.to/2g6p5dr Print instructions Rafts: No Supports: No Resolution: 0.2 Infill: 25-50% Gyroid or Cubic Walls: 3 Does not require supports, but may require a brim for adhesion.
