Dụng cụ tìm tâm cho Gridfinity

This quick to print center finder will fit perfectly in a 2x2 grid as part of your gridfinity collection.

Can be used to mark the center of a rectangle or circle up to 140mm (5 ½") wide. 

There's a slanted channel running down the centerline, with a narrow opening for the marking tool / pencil. Choose which model to print based upon the width of the marking pencil / tool:

• Superfine (0.3 mm channel)
• Fine (0.5 mm channel)
• Standard (0.7 mm channel)
• Wide (0.9 mm channel)

(If you need another size of channel, let me know in the comments)

The wide version printed in 90 minutes on a Ender 3v2, using a 0.8mm nozzle and draft quality (0.32mm layer height). You may wish to print the more precise models with a smaller nozzle and layer height, but it worked fine for my needs.
