Overall dimension will be 24" wide, using 3/4" plywood (making inside measurement 22.5" wide), and a total length of 6 feet (so both the main box and the brain box combined will fit into a pickup truck).
The height of the sides will be dependent on the with of a 4'x 8' sheet of plywood, maybe just under 12" (to account for blade with cuts).
I will build the brain box first to see what the total depth will be then can build the main box to accomodate the 6' length.
The printed parts (Drop holes, side/top humps) will be 22.5" wide, so you might want to cut the box side/cross supports to be just a little bigger for flexibility.
Note if you hook up the USB-B connector, the TX light on the board will flash when breaking the beam. On the DC Barrel jack, you have to use the onboard LED.
Brainbox frame to house the Arduino, Buck Converter, Wall Power Plugin, etc.
more text
The main box can be cut out of one sheet of 4x8 plywood using the image for reference.
Note the 22.5" side supports CANNOT be cut less or the printed parts will not fit. You could add an 1/8th or something for just in case.
I created a 2.5" spacer tool, this will be the distance from the top frame to the cross supports.
All the humps are around 1.5" tall (+14mm for drop holes) which is 1.55" total height so this 2.5" spacer gives 1" clearance at the top.
This tool also has a 1" spacer which can be used for a gap between the side and cross supports.
This stops normal rolling balls from going over the side, maximizes clearance below the drop holes to the down ramp, and allows a cover to be put on the top.

The downramp has 4mm filleted outside corners for printing.
The lower corners are covered by the side hole ramps.
The front will slide onto threaded rods connected to the Drop Holes
The gluing edge will slide into (2) 160mm threaded rods.
There are also 2.9mm holes on the bottom where you can print a spacer.
Rectangular slots for inserting 60x10x3 mm magnets, verify polarity in main hump.
The design supports a 7mm floor plank.
Cut down the center, add (2) 4.5mm holes, 80mm (6.3") (for 160mm hole) deep on each side.
Glue together with Epoxy. Can add metal hot staples to back for extra strength.
You could try using the 7mm spacer if the flooring isn't the right size and move it back from the down holes.

Droholes has a 20x20 grid hole bottom for attaching clips for wires and other items. They are 11.2mm deep. Do NOT use a screw longer than the hole, it'll buldge the top.
Print with the cutouts NOT THROUGH the holes. I tested with hole cuts its not as perfect.
Multi color .3mf setup for Black on top with black lettering and white underside.
You will need (15) 50mm pieces of #8-32 threaded rod for gluing together.
You will need (7) 50mm pieces of #8-32 threaded rod for connecting to Down Ramp.
Thread Rod total: 1100mm (43")
Use BSI Epoxy, gluing 2 sections together, then slide for final two together.

You'll need 25 sets (1 Left, 1 Right).
I kept three heights, 4mm, 5mm, and 8mm.
The "height" is the depth of the base the sensor sits in.
Drop holes have a 5mm cut out so using the 5mm base will put the laser level w/ the bottom of the drop holes.
4mm will drop 1mm which is max with the wires sticking out.
If you want 6mm, then take the 8mm and cut 2mm off the bottom.
I'm using 5mm base so the IR sensor sits flush.
I also added a 2nd color to fill in the number designating the height.

This can be printed with speakers on Top or Bottom. Originally I did on bottom but thinking of moving speakers to top so the buttons/volume is easier to use.
Also the rolling ball lines will be a little more since the LCD is less in the way.
Also, the Volume Knob has the ability to be moved up and down for personal preference... but locked in place once you cut the playfield for installation.

Pam FRAME is what the unit will screw into.
Pam Bracket will be screwed to the undermount and the frame will slide into it.
The cover (coaster) can be anything, I resized to 80mm (could be wider) and 5 mm tall (to match the LCD).
The cover has a negative stl you can place into it for the knob cutout. The knob will sit below the surface.
The undermount cutout will allow you to 'move' the unit up/down pending preference.
