TouchTyperGrid - a learning help

This is a grid that you can simply place on your keyboard to give your fingers a tactile boundary in the initial stages of learning to touch type. You don't have to glue it to the keyboard, it's stays there by itself and can be easily removed.

Fits Apple Keyboards and similar keyboards from other manufacturers (Dell for example). 

If you want it higher or thinner, just scale the z-axis in your preferred slicer.

Hope that helps and let me know if it does.
