Long project remixed from unprintable https://www.thingiverse.com/thing:1525036 by JackSpectre to make printable on fairly large scale with minimal overhangs and no risks!

Split in 2 for easy printing.
Lower base mating face recessed (needs supports) for cleaner mating at edges and 4 alignment pins.

Largest dimensions for printing are 207 X, 152 Y, 149 Z
, so most people can print it.

Setting support overhang angle to 70 degrees for upper base will prevent supports from printing in the topside vents, and still provide supports at bottom front. That slope should still bridge and print well for that short span.

I chamfered most other overhangs to below 60 degrees to eliminate supports higher up.

Horizontal and front panels had to go or this may never have been finished.

Pins, wedges, wings and keels combined in 1 file.
Left and right wings and wedges and keels are totally optional.
Slots made for keels in bottom. NOTE: My keels did not fit the slots due to .6 nozzle rounding in slots. No problem for .4 nozzle fitting. Separate meshes in slicer  and shorten the keel depth 1mm and you're golden.
Wedges and wings are meant to be placed as pictured (Circled in green) if desired. There are no slots for them, but can be glued to appropriate surfaces.

Recommended print settings:

2 walls/shells with 0.6 nozzle (faster print, but corners more rounded)
3 walls/shells with 0.4 nozzle (much slower, but sharper corners)

4 top and bottoms. If 0.6 nozzle, .3LH will be much faster and there are few slopes to notice layer effect. 

Support 70 degrees
