This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 Works with sp3, my first keyboard controlled model. There is a little playground for it. I need to say special thanks to synytsia_anton@yahoo.com and Mr. K. (Pečoler). Their creations motivated me to practice more with sketcyphysics.
