makes it easier to 3d-print in the end.
the plate and walls are still separate parts - easier to work on
separately. it is also possible to even 3d-print them separately, in
which case add a 0.5mm to clearance and plate mount Z in the params
sheet.
this makes it a lot easier to work on a part and look at it in the
assembled view by simply switching tabs. the separate file links to
the original provcase.FCStd. so, need both files to work on the assembly.
it is now possibly to simply select "exploded" or "assembled" option
from a "view" property of the top level assembly std part: no need to
manually modify the asmsheet. the property config is in the same
spreadsheet.
display standoff length now correctly offsets the LCD, the board and top
heatsink while leaving the rest in place. so, it is very easy to change
the overall height.
this change also applies 4.3inch LCD updates from 0c42295 with correct
rpi board mount screw holes, since the LCD master sketch in the
assembly is a copy.
the SSD PCB sits very nicely now. the heatsink model has a pad at the
bottom but it is not the case with the actual sink in use.
will remove it later.
the change also makes the base plate shorter, right about the size of
the display: will be splitting the box in two to allow printing within a max
circle area of 140mm diameter.
this also means the STEP file is replaced with a freecad native file
format.
the master sketch comes in very handy when designing mount and other
constructions around the LCD.
very simple, contains only the essential bits dimensions of which play
important role in the case design due to size restrictions.
there are two std parts: regular with sketches with sketches to
construct the body, and a simple refined version for the provcase
assembly.
the regular variant also has a master sketch to aid in defining
constraints in the provcase design.
all are parameterized via the asmsheet which now includes
a calculation for an exploded view.
while there, added the missing display standoffs.
what's still missing is:
- SSD board
- heatsink top/bottom spacers
- outer case walls and mount holes
