This is a parameteric corner template generator with enough templates already generated for you. The script can also generate a hanger for your templates. These templates use very little plastic, yet sturdy enough for real use. They have clearance for pen tip, thus you will not end up offsetting the corner out. In the customizer you can change all aspects of the template.

You can either print the generated templates one at a time or there is a combined version: fishy. Fishy contains templates for 10, 15, 20, 25, 30, 40, and 50mm and a hanger to hold them all. It weighs 14g! and prints under 100 minutes.

Default templates and settings for the customizer is good for either 0.4 or 0.5mm nozzle with 0.2 or 0.25mm layer height. You may want to slow down hanger.

Sandpaper the guides before writing anything on them.
