About this 3D model
This is the top front and rear edges of my computer case. They allow for 142 mm width, the size of my 240mm radiator. I used 300mm beams to connect front to back and I used 450mm from top to bottom to finish making the case. I then slid 1/8th thick acrylic sheets into the slots for side panels. The top has my radiator and it is covered in mesh. I used the parametric L connector and the 2020 makerbeam with print optimizations both scaled to 1010
