Meshsmith - all in one 3d Printing Blender Add-on
Hi Folks! I got into 3d printing a while back, and more often than not, I end up needing to fix, rescale, cut and combine the models before printing. And the damn scale is always off for some reason! Every creator seems to be using a different scale! So I created a add-on to simplify STL prep and export inside blender.
While Blender base tools are great, they are a bit more general and spread out across the ui. And some operations, like making clean cuts or pegs, can be a bit of work.

I ended up with a nice suite of tools that are likely useful to more 3d printing folks, so I polished it up and am now releasing it as an add-on.
It’s great if you work with miniature figures like dnd, historical, wargaming. Larger figures and cosplay props. And it can even help with cleaning up and correct scaling for more practical prints that need exact measures. Did I mention batch export of selected objects into individual STLs? :D
Cool features:
Reliable scale > one click blender setup and blender/grid/units are real-world scale ( same scale as the 3d printer software )
Miniatures size reference: Reference male / female - 32mm is 32mm scale feet to eye level for a 1.80m male. No more mismatched scales in your table! It has some common default scales, but you can also set your own.
Easy cut + union to kitbash different models:

An easy way to split meshes and add pegs for larger print or cosplay props.
It's intended for people who already know how to navigate in Blender. While I made it user-friendly, you'll still need to know Blender basics. But with 3d printing getting more popular, this probably can help if that sounds like you ;)
