I could render one in AutoCAD easily enough but it probably isn't necessary. I made a few adjustments to the top panel which simplifies the cutting process. The bow at the front is gone. Also all of the holes are parallel now so no funky measurements. I also drew out all the panels except the bottom fully dimensioned, since it's just a blank 20x10 sheet. The side panels have a 5 degree slope to them, should be easy enough. These two pieces plus the top will have molding so they have their corners rounded with a 1/2" radius.
A little more needs to be explained about the mounting of the trackball. The instructions call for a 3 3/8" hole for everything to fit snug but that is not a standard hole saw size so they suggest using a 3 1/2" hole instead. That causes an issue where the trim needs to be glued to the trackball to keep it in place which makes it a permanent addition to the panel. So I would greatly prefer a 3 3/8" hole. Finally for the trim to sit flush with the panel, the top panel needs to be 5/8" MDF with a 1/8" recessed area for the TB to sit in and 1/8" plexi.
There's a lot more information plus pics of the mounting in this thread to give ideas on how to do the 3 3/8" hole.
http://forum.arcadecontrols.com/index.php?topic=83988.0So here's my final want list:
Top Panel - 23" x 13" x 5/8" Corners rounded with 1/2" radius and cut for T-molding. 1/8" recess for flush mounting trackball.
2 Side Panels - 11.5" x 4.75" x 3/4" 5 degree slope, corners rounded with 1/2" radius and cut for T-molding.
Front Panel - 20" x 3.75" x 3/4"
Back Panel - 20" x 4.75" x 3/4"
Bottom Panel - 20" x 10" x 3/4"
All holes except trackball are standard 1 1/8" size
Trackball: 3 3/8" hole
Plexi: 1/8" cut like top panel
If this build is in your realm of expertise, let me know and shoot me links to your project threads with similar work if you have them. And if you need more info from me, let me know. I have this drawn out in Photoshop as a 1:1 300dpi image plus what I threw together in AutoCAD. I can provide either or both to the builder.
