This is remodeled to include a 4.95mm cutout in the sides to accept 5mm acrylic. Thankfully I have a CO2 laser cutter and could easily cut the pieces to fit perfectly. This way I can keep the sound down as well as the heat in when I print!
The front is and back are 15mm x 320mm with the front having a 25mm x 2.5mm cutout in the center to allow for the screws on the lid to fit. The sides are 15mm x 290mm.
I have attached the DXF files for the inserts.
