Enclosure

Generate toolpaths, following assumes 18mm plywood:

python3 enclosure.py --swap-axes --workpiece=front | tee amt-box-1-front.ngc amt-box-2-front.ngc
python3 enclosure.py --swap-axes --workpiece=side | tee amt-box-1-right.ngc amt-box-2-left.ngc
python3 enclosure.py --swap-axes --workpiece=back | tee amt-box-1-back.ngc amt-box-2-back.ngc
python3 enclosure.py --swap-axes --workpiece=cap | tee amt-box-1-top.ngc amt-box-1-bottom.ngc amt-box-2-top.ngc amt-box-2-bottom.ngc
python3 enclosure.py --swap-axes --workpiece=side --port-enable > amt-box-1-left.ngc
python3 enclosure.py --swap-axes --workpiece=side --port-enable --port-mirror > amt-box-2-right.ngc
python3 enclosure.py --workpiece=support | tee amt-box-1-support.ngc amt-box-2-support.ngc

Prepare approx 40cm by 90cm piece of plywood to accommodate following:

Mill support (8cm), this should leave enough room for clamps
Mill front (30cm)
Mill side (20cm)
Mill top (20cm)

Cut another 40 by 80cm piece:

Mill bottom (20cm), again this should leave enough room for clamps
Mill back (30cm)
Mill side (20cm)

Glue parts with wood glue (PVA). Finish with

Filter

Use single sided PCB, mill traces with the supplied circuit. Use possibly liquid tin to increase the cross section of traces.
