Pulsar 2849 box to table insert supporting geek bits and vertical storage

Pulsar 2849 insert.  Most of it is box straight to table.

 Each STL file name has the number that needs to be printed, and print profile is set to minimize filament (as was the insert).

 There is an optional tray/box with lid.  2 of them will fit on the open side of the insert exactly and can be there with or without the lid.  I put a picture showing the pieces alone on the top of the insert for reference.

 All the board pieces go on top of the insert which is flat like the bottom of the box.  Just stack the cardboard evenly over the top (it always comes out the same height).  And the rules will fit on top with no lid lift.

 IMPORTANT:  I included colored (painted) lids in the 3MF, but also the single-color lid that can be printed 4 times as well for those who do not care for or want the color.  Skip the colored ones if you print the gray one 4 times and skip the gray one if you print each colored one.
