X-Wing Tournament Tray for Harbor Freight: Some Tweaks

Some tweaks to thedustycelt's excellent tournament tray! I'm basically tweaking to:

• make it easier for me to print (some adhesion issues here)
• fit my sleeved full-size cards
• fit into a small Harbor Freight organizer

Here's what I've done:

• redrawn the accessory tray in OpenSCAD b/c I'm familiar with that
• made the bottom magnets optional (in the OpenSCAD)
• increased the corner radius
• slightly inset the bottom to fit better into the bin

Updates:
Dec. 19, 2019 -- New version uploaded. This one has a slight bevel of sorts around the top and has an increased card space based on a test run. It's a snug fit in the box (which is fine) and works!
