This bracket lets you mount a tablet to the side of an Ikea LACK enclosure, or any similar enclosure.
I use Octoprint and my tablet is dedicated to running Printoid, so it acts as a control panel for my printer.
Be sure to edit the design to fit the height, width, and thickness of your tablet!
The overhangs are there to make it easier to print supports on the build plate only, so that you can bridge between them. Otherwise, you would need to print supports inside the model, and that makes it harder to remove them.
