It appears that the Lyman Filament Extruder v6 download from thingiverse includes parts and an assembly manual for two styles of constructing the main housing, one of which seems to be superseded by the other, rather than simply being optional variations.
The motor and auger housing has several sets of files seemingly intended to allow printing in sections to combat warp. Need for this on the D3D specifically may be require one or the other? The main case likewise has mesh files for a completed assembly, and Hugh notes on page 4 that in the images he printed the case in one piece and is attaching the base, however it appears to me that the complete case files do not have mounting holes for the fan bracket, though this may be unnecessary and is easily remedied. I have not listed these files however because they require a large print bed.
Antiquated build of case is portrayed on pages 15 and 16. This appears to be much more complicated to print and has no clear advantages to me. It has tab and slot construction and keyhole mounting points. It accommodates all of the same controls.
This version listed below appears to be the version shown in the construction photos, which leads me to believe it is the newest version. It consists of 21 parts, though if you print the auger case in two parts it is 22 prints. Printing the entire extruder housing (auger+motor housings) in one piece will reduce this to 20 but that may be too big depending on printer capabilities.
Parts to Print (Begins Page 17 in construction manual)

Spooler
Spooler appears to have a ‘stable build’ and no legacy parts that need to be filtered out. These parts can be printed in their entirety as well as traced for simplification.
-Any potential advantage to slot and tabe case design?
-can the extruder case (auger plus motor base) be reliably printed at once?
