Measuring and fitting
-
Digital calipers
Every pocket in the new head came from caliper measurements: the screen, the camera, the XIAO stack. Ours are Mitutoyo, but any steady 150 mm pair will do.

Craft knife
For pushing out the sacrificial skin in the leg links and shaving a pocket corner that came out tight.

2 mm and 5 mm drill bits
Turned by hand, not in a drill: they clear the little support plugs in screw counterbores and the skin in the leg links.

Precision screwdriver set
Everything is M2, M2.3 or M3 Phillips. A PH0 and PH1 cover it.

Glue and cleaning
-
Two-part epoxy
The fix for a loose magnet. Superglue is brittle and grips nickel plating badly.

Gel superglue
A few dots hold the eye and camera rings on the face.

Isopropyl alcohol
Wipe a magnet before epoxy, and keep the build plate clean.
Search Amazon UK -
Fine sandpaper
Scuff a magnet's plating so the epoxy has something to hold.

Printing
-
A filament dryer
Support For PLA/PETG picks up moisture and then strings. Bambu suggest 12 hours at 60 °C. We use Bambu's AMS HT, but a standalone dryer does the same job.

Bambu Lab H2D
Our printer. Any printer that does PLA and TPU can make the duck from Luwu's files. Our tuned print file needs a 0.4 mm nozzle on both sides of an H2D.
