Parametric Customizable Foam Core Corner Brackets

thingiverse

I was considering testing whether a foam core wall around my 3d printer would dampen some of the noise in another room. Initially, I created a basic part, but took it further by making it parametric with several adjustable variables. Users can create 90-degree corners using either two or three connections, and they can also alter many individual dimensions to their liking. They have options for producing corners at 90, 120, 72, 60, 45, 40, 36, or 30 degrees. This allows users to attach foam core or another robust flat material and construct enclosures with 3, 4, 5, 6, 8, 9, 10, or 12 sides. I only used it for a 4-sided configuration but added the other possibilities while they were still on my mind. Others may need to fine-tune their printing settings for the three-corner version, as it prints at a 45-degree angle to eliminate the need for additional support. My own print of that design was a bit rough but still functional, and I applied six-millimeter brim to that print. To use this design with a material other than foam core, users should change the Gap variable to their desired width, then add a little extra space if needed. I used 4.5 millimeters to accommodate the foam core I have available. The customizable variables are all clearly documented as to their purpose, and users can also open it in the Customizer.
