Tuna Tin S (7), 1st try cabinet

Here's the first try on the cabinet. My son Sam and I designed it on Fusion 360, and I printed it out on my 3D printer.  See the photo below. The hole for the encoder was located in the wrong place. As can be seen,  I opened the encoder opening up with a nibbling tool.  The back view is below

The PCB is pushed forward to lock into slots behind the front panel, and two mounting screws at the back corners hold the PCB down. I didn't leave enough room under the PCB for the wiring, so we'll have to increase the dimension.  I used M4 machine screws as self tapping screws and they seem to do the job.  We'll try the corrected version tomorrow.
