I made it at TechShop.
Spray painting multiple colors
Step 1: Mask
Mask off everything to not be painted with the blue tape.
Step 2: Paint
Paint the unmasked area. Turn on the ventilation. I like to do a light dust coat and then follow up with a full coat that looks wet after spraying.
Step 3: Let Dry, Repeat Fo R Other Colors
Repeat for each other color. Apply clear and let dry, you're done!
