Help Strengthening Posts

[fjwolz19 0]

I am trying to print a mounting bracket I designed for something, so it has some posts sticking out of it that slide into slots on the device. When I print it, underneath the posts the bracket is hollow which makes them too weak to hold the device and they break off. The inside of the posts are also hollow, which I have found I can adjust with the shell thickness, but even with a pretty high shell thickness, underneath the posts are still hollow. What do I need to adjust to correct this?

Thanks for any help!

Hi and welcome,

I'm not sure i understand what you ask but to fill up the inner parts of the print there's the infill parameter that you can change. Usually 20% is already strong. If it needs to be full then 100%

looks more like a cad problem. Inspect your model with the x-ray or transparent view (upper right), red areas are bad...
