3D Printed Tool Ruler

Overview

The ruler includes:
1. Double-sided measuring, convenient for both left- and right-handed use.
2. Screw size measurement for quick screw identification.
3. Hexagonal opening for use as a hot-end wrench, compatible with most M7 nut sizes on the market.
4. Optional heated bed leveling function; after circuit soldering, it can be used as an auxiliary tool for manual hot-end leveling, judging the distance of each leveling point by the state of the LED bead illuminated by pressing the microswitch on the hot end.

These are functions I commonly use when debugging printers. It's

a very simple project, my first time publishing, so please be kind.

[b]First of all, this seminar started a little early, but the information is very practical. It is in Chinese. I guess analog electronics friends will love it after seeing it! Then download it slowly,
Modelsim post-simulation problem
Modelsim can simulate before, but not after. Is it a software problem or is it not completely cracked? I can guarantee that the operation of the simulation process must be correct.
