So, I finished my project and want to print it.
Problem is, I wanted to have a 5mm thick wall, but somehow SW doesn't let me thicken it...
I need to thicken it to the inside so I could print it (it need to be hollow on the inside to cut production costs and time), what would be the best method for this?
As others have mentioned you have minimum radius problems, which I will let you fix.
I wanted to show you a method of getting the thickest part from the existing geometry.
1. Convert your surface body to a solid. Start by doing a filled surface for the bottom opening.
2. Before doing surface fills for the 3 holes, add a Plane and create a sketch of the 3 holes using Convert Entities. Then fill those holes.
3. Split the solid body and delete half.
4. Use Check to identify where there is very little radius of curvature. Delete & Patch that surface. (You should instead be editing your surface features.)
5. Mirror body to get back to original.
6. Use Check to identify the current radius of curvature (1.56 mm).
7. Use Shell on the bottom face with 1.5mm wall.
8. Use the sketch in step 2 to cut those 3 holes.
