Self feeding open source filament pelletizer with PET plastic bottle for window

I still wanted to have a window, and to verify that the parts were clear. I don't have a CNC to cut the out of acrylic, but PET bottles readily available. Modified the original file to allow 2 windows to see both sections. I used the printed model to trace on PET bottle, and cut with scissors, and drilled the holes. Used 6mm screws to mount. Model is easy to scale in the Z direction if thicker is needed. Printed in PLA.
