These commits were pushed to hw/fix-gills-mirror after #59 had been merged, so they never reached master. They are rebased here on master, which now includes #61.

Changes to the cradle, from the first print:

  • the stop plates go in tab up, and the wire is soldered on top of the tab; the tab slots through the floor are removed;
  • each end gets a notch next to the tab (wire_notch), so the wire runs along the cell in the open top;
  • the radial fit goes from 0.4 to 0.8 mm (cr_fit); the first print only just went into the stem;
  • the plate slots are sunk 1.5 mm deeper (bt_sink): 1 mm measured, plus 0.4 mm because the cradle radius is smaller;
  • three side windows per flank (cr_win) cut the solid volume from 16.6 to 12.2 cm³.

Also:

The cradle and stem export without errors, and the asserts pass after the rebase. print/mushroom.3mf is not regenerated, since no reprint is planned: run ./export.sh before the next cradle print.

Measured on the print: the plates sat 1 mm too high in their slots.

From the first print: the stop plates go in tab up, with the wire
soldered on top. The bottom tab slots are gone. Each end gets a notch
next to the tab so the wire runs along the cell in the open top.
Radial fit goes from 0.4 to 0.8 mm. The slots sink 1.5 mm (1 mm
measured, +0.4 for the smaller radius). Adds a cradle_view render part.

Three through-windows per side under the lips that hold the cell. Floor,
rails and posts are kept. Solid mass goes from 16.6 to 12.2 cm3.
