Printable Slidecam V1 (Extendable to any length)!

This glidecam is just something I made for easy shooting on the go. The center bolt to hold the camera on is just a 1/4" bolt and the rods are 8mms from an old printrbot. I've included a small hole in the cart for a device to pull it along with string. Enjoy!
