NO FLEX - Gaggiuino Top Front Screen Mount

--------------------------------------------------------------------------------------------------------------------------------
Update – 07/01/2026

• Uploaded Rev 3 of BACK PANEL and OUTER SHELL

• Rev 3 increases the thickness of the screen surround on the OUTER SHELL to improve print robustness across a wider range of printers and settings

• Corresponding geometry updates were made to the BACK PANEL  to maintain correct fit and alignment 

• Verified updated design by printing with extra-daft settings (0.28mm layer height & high speed) with no issues

--------------------------------------------------------------------------------------------------------------------------------
Update – 24/09/2025

• Replaced the original BACK PANEL with BACK PANEL_REV 2

• Rev 2 features a wider and deeper cable slot, making routing easier

• For the OUTER SHELL, I recommend printing with supports set to a 35° threshold - this reduces support material and makes cleanup simpler. See image below for further detail

Description

A top-front screen mount for the Gaggiuino display. The screen is positioned at a fixed viewing angle matching that of the Decent DE1, making it easy and comfortable to use. The mount  doesn’t flex when pressing the screen, and pump vibrations don’t wobble it. The wiring exits  from the rear of the mount and routes directly into the machine, making cable management very discreet.

The mount is constructed from two 3D printed parts: the Outer Shell and the Back Panel. These are secured together using four threaded inserts (GE-M3x57-001) and four M3 x 6mm ISO 4762 cap head bolts. The assembled screen mount rests on the top front edge of the Gaggia Classic Pro and is held in place by the three rocker switches.

Assembly Instructions

1. Insert threaded inserts
   Using a soldering iron, carefully insert the threaded inserts into the holes on the back of the Outer Shell.
   
   

   

   
   
    

2. Install the screen
   Place the screen into the Back Panel. Route the cables carefully as shown in the reference images.
   
   

   

   
   
   Pay particular attention to the bottom left corner of the screen — ensure the black and red wires are routed beneath the screen as demonstrated:
   
   

   

   
   
   A toothpick can help guide the wires into the cable routing slot.
   
    

3. Assemble the mount
   Attach the Back Panel (with screen installed) to the Outer Shell using the four M3 x 6mm cap head bolts.
   
   

   

   
   
    

4. Prepare the Gaggia Classic Pro
   Remove the warming plate by unscrewing the two screws located towards the rear of the screen. 
   
   

   

   
   
   Next, remove the three rocker switches by first unplugging their cables—be sure to note their original positions. To release the switches, press down the tabs on top; a flat-head screwdriver can be helpful for this.
   
   

   

   
   
    

5. Fit the screen mount
   Place the assembled screen mount onto the top front edge of the Gaggia Classic Pro. Push down on the screen mount to ensure it's fully seated. You will know its in position when the switch openings on the mount and Gaggia line up -  as shown in this image:
   
   

   

   
    

6. Reassemble the switches
   Replace the rocker switches, and reconnect their cables
   
   

   

   
    

7. Replace the warming plate. Note that the screen mount slightly obstructs the warming plate as it goes in. So to fit it back, first put the water filling funnel in position, then rotate the warming plate into place. When the plate contacts the mount,  press down to flex it and get it in.
   
   Put the funnel in position and rotate the plate until it comes into contact with the mount:
   

   

   
   
   
   Push down to flex the warming plate and continue to rotate the warming plate into position:
