remove the frame posts from panels, more trouble than they're worth
the panels had posts that would drive into the frame column (the frame
column needing to be a bit wider at the top and bottom accodringly).
this was an attempt to assist the friction fit of the whole stick in
tandem by having the panels contribute to the position and rigidity of
the frame pieces. in practice I think this didn't really contribute
anything major to that problem, and instead made the panels hard to
connect, and way harder to remove, while also having a visual defect in
that the panels were usually separated slightly due to having to fit
exactly in the frame columns.

this goes back to the old design where the base panel is a flat sheet
and the frame column holes are uniform. everything seems nicer this way,
and the overall build is simpler.

don't recommend fiddling with the initial layer height/width
doesn't seem to be any real gain in changing them, having done more
prints with those settings and with stock settings.

things might have actually been warping a bit more with the higher temps
at least it's seeming that way with some Bambu matte PLA

## Putting a BSS Stick Together
Assembly of a stick is pretty straightforward, but there are some choices that can make it easier or harder. The
following is the most consistent way I've found to put one together. This is assuming a v4.1 or beyond stick, with two
following is the most consistent way I've found to put one together. This is assuming a v4.2 or beyond stick, with two
panels to make a long standard stick, and the frame made of pieces.
1. Prepare the frame top pieces --- `frame-piece-top-{left,right}`: this is your best shot to get auxillary buttons,
1. Prepare the frame top pieces --- `frame-piece-top-left-or-right`: this is your best shot to get auxillary buttons,
panel connectors, and the like installed, so do it now, and give them a good tighten. You shouldn't need to adjust
these again, so finish their installation while the pieces are free.
1. This of course includes decorative plates --- e.g. `misc-decorative-plate-aux-control-three-button-cluster` ---
you may choose to use. These are held to the top pieces by the buttons or component mounting screws.
2. Start the top panels --- `top-panel-(inset|overhang)-*`: you want both to get the components installed now
when it's easy, and to make sure that the overall assembly works with your components, so again get your buttons,
lever, etc., in place.
lever, etc., in place. You can secure them at this point.
1. If you are using a button decorative plate that spans two panels --- e.g.
`src/misc-decorative-plate-dir_arc-plus-w-30mm-and-sega-2p-plus-one` --- don't tighten the buttons all the way,
as you may need some wiggle to align the panels to the frame in a later step.
2. If the above isn't the case, you can tighten all your buttons now.
3. If using a lever, don't forget the lever mount spacer --- `src/misc-lever-mount-sanwa-seimitsu` --- if you want
`src/misc-decorative-plate-dir_arc-plus-w-30mm-and-sega-2p-plus-one` --- take care to align the two panels as
tightly as possible, and accurately, as they will be hard to adjust once everything is secured and in the frame.
2. If using a lever, don't forget the lever mount spacer --- `src/misc-lever-mount-sanwa-seimitsu` --- if you want
it, and tighten those mounting bolts now as well.
3. Create the frame box by combining your `frame-piece-*` parts together. This will be relatively stable just via
friction fit.
4. Rest the frame top-up on a desk, and put the standoffs through the holes.
5. Insert the top panels into the frame. The friction on this will probably be tight, and you may not be able to muscle
it in on your own. Get the panel posts at least partially into the frame columns, in any event. If you get all the
panels completely in, the next steps will be easier, but it's not imperative.
6. Start the bolts for the top panels. Get it so that the bolts catch the standoffs, but don't tighten them completely.
You will want some wiggle when connecting the bottom panels, which is maybe the hardest part. Depending on your bolts
and how deep into the frame you got the top panels, you might need to push the standoffs up the column in order to
catch them with the bolts.
4. Rest the frame top-up on a desk, and put the standoffs through the holes. This will probably be tight, and you may
even need a rubber mallet or similar to drive the standoffs through the holes.
5. Insert the top panels into the frame.
6. Insert the bolts for the top panels, make any last adjustments, and tighten them.
7. At this point you have an open box with access to all your components. Do all of your wiring.
1. Tighten the buttons and etc. if you didn't in step 2.
2. TEST YOUR BOARD AND COMPONENTS NOW! You don't want to have to undo the rest of the steps for something trivial,
trust me.
8. Insert the bottom panels into the frame. This may be difficult. If you got the top panels into the frame in step 4,
and left the bolts loose in step 5, you can make the standoffs rise outside of the frame column, which makes it
easier to line up the standoffs with the bottom panel posts.
9. Drive the bottom bolts into the standoffs. You probably don't have the panels all the way into the frame, but if you
can at least get the standoffs in the posts, you can catch them with the bottom bolts, and then let them guide the
panels into the frame.
10. Tighten all the bolts. If you didn't get the top panels flush in step 4, you can apply the same logic as in step 8
and tighten the bolts to guide the panels into the frame.
8. Insert the bottom panels into the frame.
9. Insert the bottom bolts for the bottom panels, and tighten them.
In the end, this should be extremely sturdy. None of the frame or panels should be loose at all, and you should be able
to move, flip, gently toss, etc. the stick without anything moving or feeling loose.

seem to have issues with filling curves and you still want to try to maximize contact with walls. Concentric is great
here if you dial it in.
Panels may have tiny gaps against the circular button cutouts; this is largely not a problem as buttom rims, decorative
plates, etc. will cover it up. However, I've had some interesting results with:
* Initial layer line width: 0.42mm (down .08mm)
* Initial layer height: 0.25mm (up .05mm)
* Initial layer nozzle temperature: 230°C (up 10°C)
* Initial layer bed temperature: 70°C (up 5°C)
* Initial layer pattern: concentric
These are good defaults and print awesome parts, with the only exception being the top panels, which benefit from using
a Hilbert curve initial layer pattern instead of concentric.
