This robust stand has adjustable X and Y heights, allowing you to use USB microscopes for larger items.

The stand also offers enhanced stability when taking pictures with the snapshot button, cleverly manages the USB cord, and is adjustable for left and right-handed users.

The stand was developed for Plugable's USB2 250x microscope http://plugable.com/products/usb2-micro-250x.

I highly recommend printing it at at least 50% infill, 100% is best. This makes the stand heavier and improves it's stability.

Here's a blog post detailing more of the features and design process: http://plugable.com/2015/09/03/robust-and-adjustable-stand-for-plugables-250x-usb-microscope

Designed in SolidWorks.

Sized to print on a 6x6x6 inch bed.
Print at 100% infill. 50% is lowest you should go if print time is a big issue.
Print the arm piece with a brim to make sure it sticks to bed.
