I'am proud to present my own right & left hander fingertip GT1P shell creation for zaunkoenig.co m2k & m3k internals.

GT1P by ㄷㅇㅇㄴㅆㅇㅁㄹ

Thanks to tyuhn for the inspirations.

Please look at the pictures. I used gpx screws cause i only got the m2k & m3k pcb and not the shell with screws. Also hot glue the sensor prism like you see on the last picture. It removes the need for a sensor prism housing which also removes overall weight.

U should consider sanding the click area where it touches the switch and use some alutape / mylar tape e.g. to have the best click feeling. You can also try to put on thin dots (height below 0.8mm, better 0.6mm). I personally did my own mylar tape dots with 2 layer of 3M 4828 0.15mm + 3m 9495 LE 300LSE with a perforator).

Stay tuned & please follow me here & on x please: coolm0dz

Instructions:

• Print in PLA with support where needed. Best use 0.20 or 0.18 layer height. 15% infill for best sturdiness. 5% for best weight.
• I prefer Spectrum PRO PLA Black. Gives best details in print.
• Lube the slide in plugs of the main clicks with lubricant so they slide in easier. I use Synco Lube from Super Lube.
• If it is too complicated to slide the buttons in/out just widen the slide in a bit with a flat screwdriver or use a thin nail file. Sometimes it is very hard to get the buttons out. Sorry for that ;) You can also push out the clicks with a thin 0.8mm flat object or thin nail file from the bottom. If slide in of your parts is still to tight use sandpaper or nail file to reduce the end thickness a bit of the clickslide in parts. https://twitter.com/i/status/1728850591361995154
• Do not screw the screws too tight. It can damage the shell or make the base warp.
  But if screws are too loose click perfomance can be worse. So find a good way.

Version printed in PLA with Prusa i3 MK3S+ & BROZZL nozzle Ruby for E3D V6 0.4mm.
If you want to get it more weight reduced use ABS. -25-30% weight.

Be aware that it is a free mod.
I am not responsible for any damage or harm you do to yourself or your parts ;)

Weight: 9.4gr base, 2x 1.7gr mousebuttons, 3.23gr scrollwheel pcb, 5.18gr main pcb = 21.21 gr (PLA) . There is still huge weight loss potential but i will first test it as it is now.
