Housing fasteners:
The housing was designed for 7 M2.9x6.5 self-tapping screws. These are the same screws Gaggia uses for attaching to the plastic fill funnel (PN DI7981P2.9X6.5I or 996530054164). Component screws (qty 2) must be no longer that 1/4 inch / 6.5 mm. Outer housing screws (qty 4) must be no longer than 1/2 inch / 12.7 mm.
If you just want to blindly order off of AliExpress then this is an option (50pcs M3, 6mm): https://www.aliexpress.com/item/3256802230982244.html
Otherwise, any of the following screws will work (get whichever are available in your area).
Accessories:
The cable strain relief is fairly self-explanatory: Zip-tie it to the cable bundle(s) just inside the housing pass-through to prevent wires from getting pulled. Don't bend the tie mount post - the part is designed to be strongest in the direction of the cables, not across.
The stripboard mount slots into the housing after soldering but before the expansion board is screwed down. It's removable so that those who still want to use Wagos, solder bundles, etc. still have room to do so. Max stripboard size is 5 rows x 8 holes plus the half edges (or 16.8 mm x 23.2 mm) as shown below. Note that it is shown unsoldered for clarity - stripboard install should be done post-assembly.
Recommended Print Settings:
PETG, 0.2 layer height, 2-3 wall lines, 235 C nozzle, 85 C bed, 80 degree support overhang angle if you're not confident in your bridging (see image recommended supports). 20% gyroid infill. No adaptive layers.
