This is a guide to throwing a monster ball straight in Pokémon GO. The grooves cut in the guide will help you to measure the distance to the target. This will greatly improve the accuracy of your throws.

The original file has been designed to fit the iPhone 7 in its soft case. If you are using a different smartphone, please re-set the output size (X and Y) on your own slicer before printing.

I recommend to use transparent filament and print it setting 100% infill so that you can see the screen easily.
