Blender Issues

[jsquires0924]

I'm new to 3D printing and I'm trying to use Blender to edit a Samsung Galaxy Flip 5 phone case 3D model adding a cylindrical ring as a guide for MagSafe. Trying to measure and center said ring isn't coming easy at all. If you can offer adivce, I'd greatly appreciate it!

Have you tried the alignment tools? There is a built in align tool add-on (extensions in Blender 4+) that needs to be enabled to use.

It is clunky and its a hit or miss of it doing what I need it to do most times but it is there.

Other than that, alignment is just making sure your point or origin are in the appropriate places for both objects.
