These instructions are for all STANDARD Logitech G304/G305 based mods.

 

You can find G304/G305 disassembly instructions here.

 

 

 

Parts required
Top shell, bottom shell, 2x clips, magnetic adapter, AAA USB battery, mouse feet, redrill screwholes if needed: Bottom 4 screw holes are 1.8mm, all other ones are 1.3mm.

 

 Tools required
Small screwdriver: Known as Phillips screwdriver

 

Hot swap PCB

The recent MOD-KITs came with the hot swap PCBs. Simply push the Kailh 4.0 in the PCBs in the correct orientation. [ Depending on the version and production quality of the G305 PCB, the tubes of the hot-swap PCBs might not fit through the G305 PCB very well. Filing the holes or using the screwdriver to increase their diameter or using a decent amount of force might be needed. ]
 
 
Screw types
From left to right: Bottom screws, side button screw, mid screws, switch screws
(Save the small screws for the end!)

 

[1] Add on/off switch

Pay attention to the orientation!

 

[2] Add PCB and fasten

Stop tightening them once the screw heads touch the PCB. They cut their own thread and we don't wanna destroy it by over-tightening the screws!

 

[3] Add mouse wheel

Insert the mouse wheel in the encoder and add the small spring. Make sure the small spring sits in the small grooves

 

[4] Add side buttons
..in their slot. All the way! 

 

[5] Fasten the side buttons
Take care not to over-tighten the screws!

 

[6] Bend side buttons inwards
Give them a bit of curvature

 

[7] Add sidebutton PCB and plate screw
Since we bent the side buttons, they should already activate the side button switches. By bending them outwards gently we can have them in a position without any gap. When you don't have a gap, add the side button screw.

 

[8] Add mid screws to the clips
Fastening them all the way is the way to go

 

 Add a mid sized screw in each mouse button. Screw them all the way in. If you want more Post-travel later, you can extend them.

 

[9] Add the clips to the PCB
Make sure the holes are properly aligned. It's possible that the gap in the clip still has left-over powder from the print.

 

[10] Add micro switches 
Fasten the switches to the clips using 4 mid sized screws

 

[11] Connect the switches to the PCB
Pay attention to the orientation of the pins

 

 

If you have a P-SL SQ, MQ or LQ , P-GP LQ button cell MOD-KIT please continue following instructions here.
 
 
 
[12] Add small battery spring - red cable
 
[13] Add large battery spring - black cable

 

[14] Add battery
Pay attention to the battery's orientation!

[15] Add magnetic adapter with the cable
You will need more force than you think. Check if the battery is charging before you continue.

 

[16] Connect the battery

Plug in battery cable, pay attention to it's orientation!

 

[17] Add the screws
Add large screws at the bottom (or on the sides with newer versions)

 

Two large screws in the front

 

3 or 4 Small screws on the places marked in the picture (switch screws)
 
[18] Add mouse feet
Add mouse feet to your mouse as shown in the picture
