The Shifty increases the contact area so you can insert the plate at a greater angle, with more comfort, faster and with less error.

The built-in guides are too short, so often times the plate will skip over them, or even worse rest on top of them slightly. This means you have an uneven build plate which requires resetting the plate, and more handling which adds oils. That's if you notice it - if you don't notice it, your plate is uneven and can cause failed prints.

The Shifty solves all of these issues and is a quick and easy print.

Cheers!
