This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 Not a totally faithful rendition, but close enough in size and features. Even has the vendor specs sticker on the bottom. Credit to “Wildman” for the screw-knob terminal posts for the DC Input. I would thank you, but there’s no way to contact you and your name is too generic to find you.
