3D Printing Forum

I am trying to increase the thickness of the base and the sides of a part. I have tried many settings, but each print is the same. Software Ultimaker Cura. I have attached a .stl of the object.
Please help.

Assuming you don't have access to a stp or other solid model file. The way I would do it would be to import into cad, convert to a solid model and make the changes wanted. Then export as a new stl file.

Yes that is an option, however there are attributes in the Ultimaker Cura software that suggest that the thickness of the walls and top and bottom can be changed. It is interesting when I increase the values on those attributes the amount of time to print the object decreases. I do not understand how this is suppose to work.

I guess I cannot do what I wanted, to increase the thickness of the sides and bottom of the part in this picture, in Ultimaker Cura. The current part is too thin that it cracks when the bolts are tightened. I thought a increase in the thickness might make it stronger. This is the concensus of participants in two 3D forums. I shall have to go back into the CAD software to remake the model. New challenge since all I have for that model is the .stl. Thanks everyone.

Thank you all. I did as you suggested, I imported it into Blender and changed the thickness of the sides. Followed these steps.
The easiest way to add thickness to a model is to use the "Solidify" modifier.
• Select your object, then go to the Modifiers tab of the Properties editor.
• Click "Add Modifier" and then choose "Solidify" from the Generate section (Blue box).
• Increase the thickness to however thick you desire. 3.0 is a good starting point.
• If you want to make these changes permanent you can hit "Apply." This is not necessary though, and leaving it as it is will allow you to edit the modifier later.
