Tamiya Mini4wd wheel piercing tool UPDATED

This tool allows you to drill a straight hole into mini4wd wheels. This allows you to use 72mm shaft to ensure the wheels are straight and balanced.

Print the tool you need (there are 3 versions for 20.5mm, 23.5mm, and 25mm wheels), insert the wheel, then pierce slowly from the top using a hand tool and a 1.8mm bit.

Print the tool again when you feel the hole has become too loose.
