Address Writing Guide

A vertical-writing guide for Japanese long envelope size 3 (Nagagata 3). Following the guide, you can write an address neatly without it slanting.

When using it, align the bottom edge of the tool with the bottom edge of the envelope. Adjust the position as appropriate. The original remix source had sharp corners, so the corners were rounded in this design to make it safer to use. Remixed from https://www.thingiverse.com/thing:4206750
