+Well, here it is; the super tedious part. Pictures of work in the mechanical section each represented about 30 minutes of work. Each of the following pictures represents about 1-2 hours of work.
+Mounted up the electronics to the acrylic panel.
+On the left is the power supply and the solid-state relay, and on the right is the Raspberry Pi and BTT Octopus mainboard.

+Shortened stepper wires and crimped JST connectors and wired the 24-volt lines between the power supply, mainboard, and relay.
+The stepper wires included in the kit were too long and they were terminated with the wrong connectors. While they would have worked, the connectors would have been easily removed by mistake and the wires would have been a mess.

+Printed a power socket housing and added in a fused socket with a switch.
+{{:projects:ratrig3dprinter:pxl_20220517_030355183-min.jpg?400|}}
+Added 120-volt wiring from the socket to the power supply and relay.
+{{:projects:ratrig3dprinter:pxl_20220517_030345741-min.jpg?400|}}
+Crimped custom connectors and wiring for the BLTouch and ADXL345 accelerometer.
+{{:projects:ratrig3dprinter:pxl_20220518_030428478-min.jpg?400|}}
+Added ground wires and a 24-volt socket and adapter to 5-volt USB to power the Raspberry Pi and tablet.
