Filling in my design and im not sure why.

[Zman07 0]

Hello all, I have attached two files in which I want to print. It needs to be hollow but I can figure out why its not coming out hollow. Its a tool I am trying to design for myself and I'm not very savvy with blender nor how to fix what the issue is. If anyone could fix it or tell me what's wrong i would appreciate it. Thank you.

The polka dot areas show where your model is missing faces:

Your model has almost no faces on the inside (and a few that are on the inside but not the outside). Cura tries to compensate for this by filling the areas.

 

Blender isn't the greatest tool for producing models to be printed (CAD software is) but I know it can do something like this... I just don't know how because I've never used it much, sorry 😞
