Gaggiuino Gen 3 Screen Housing

There is one main screen housing design, multiple mounting options. 
The Front mount is compact and needs fewer parts but is at a fixed angle and can be low for taller people. The Rear mount takes up more space and uses more parts, but the angle is adjustable. The funnel mount is the most complex but has great screen placement and compatibility with Silvia as well.

Parts needed

Front Mount:

• 6 20x10x3 mm magnets (double stack). 
  • https://www.aliexpress.com/item/3256803170039630.html

Print settings: 

PETG (PLA and ABS won't work), 0.4 mm nozzle, 0.4 mm line width, 0.2 mm layer height, 3 wall lines recommended for Mount_Rear and Mount_AdjustablePlate (2 or 3 wall lines are fine for the rest), 20% gyroid infill. If your printer can't print hit tolerances of +/- 0.15 mm these prints may not work.

A Note Regarding Flow Calibration: 
I have great respect for Ellis' Print Tuning Guide and agree that overall flow should not be tuned via wall thickness calibration. However, if the printer is tuned and wall thickness matters in a design then the simplest way to make sure walls aren't out of spec due to any remaining layer wobble or inconsistent extrusion is to do a wall-based flow calibration and adjust wall flow only. I would recommend doing so before printing this design.

Mount_Front - Pay attention to where the Z seam is and don't have it on an unsupported overhang. 

Mount_Funnel_Cover_* - Minimum 3 bottom and 4 top layers required.

Front Mount:

Route wires outside the housing, between group head and steam wand as shown. Use Kapton tape to secure.

Adjustable Plate assembly (for Funnel and Rear mount):

Changelog:

• 2024-06-13 - Printability improvements to ScreenHousingBack.
• 2024-08-25 - Beta screen housing is primary, old screen housing is now the Dev screen housing (due to connector access for development use)
• 2024-09-02 - Added STEP of the Mount_AdjustablePlate. This interface piece allows anyone to create their own mount that will work with the screen housing.

Print Settings: Make sure the gaps on the print-in-place parts aren't getting joined. If they are, make sure the gap closing radius is 0.03 mm or less. 

Print in place cover separation: If everything is ideally tuned you shouldn't need to do this, but if things are a bit tight on the microSD and USB-C access covers you can flex the housing to separate them.

Latch: The ScreenHousingLatch gets inserted into the slot behind the Gaggiuino logo in the ScreenHousingBack (insert round side first)
