Description

An ultralight chassis for the BambuLab Wireless Mouse Components Kit, based on Optimum Tech's ultralight modkit and designed to be printed in PLA. Features screw-in reverse triggers, and uses an AAA battery instead of AA to further reduce weight. Also, because the triggers are separate parts, you can mess around with printing them in different materials from the rest of the mouse.

NOTE: The triggers are the hardest part to print. I've put everything on one plate to keep things organized, but if you're worried, consider printing them separately.

Rough assembly instructions after printing:

Add lens and on/off switch to the bottom of the base, following Bambu's assembly guide for orientation (a copy is attached here, for reference). Also attach the scroll wheel as directed.
Plug the battery connector cable into the circuit board, and pass the connector cables under the board.
Push the battery terminals into their respective slots, then align and press the circuit board into the base with the cables underneath. Everything should click down into the lens/switch.
Partially screw 3 screws into the two triggers and one spacer, then put them over their respective positions (see images) and fully screw into the base to lock down the circuit board.
Insert battery.
TEST IT IN YOUR HAND TO SEE IF YOU ACTUALLY LIKE THIS DESIGN. See images for a sample of how to grip it. I'm putting this here because:
Add the 4 mouse feet to the bottom, see pictures for positioning. DO NOT DO THIS STEP UNTIL YOU'RE SURE YOU LIKE THIS DESIGN, the feet get wrecked pretty badly if you try to pry them off after.
Turn on mouse, enjoy.

Thank you for uploading the step files for this one. It allowed me to easily modify the mouse buttons to work with some microswitches I replaced the original buttons for (which coincidentally also allowed me to print those areas without supports). I also extended the length of the buttons and added fillets to many of the angles, making them look a bit smoother. Mainly, I appreciate that you designed the frame for an AAA battery because I have rechargeable AAA batteries but not AA batteries hahaha 😅

Hmmm, I did prototype longer triggers, but backed off because I had to reverse bend them pretty far to replace the battery and it felt kinda sketchy. Is that an issue for you or not?

@gaudystead

Replying to @vsin :

I had to *slightly* bend the right trigger upward a bit to get the battery in, but I'm guessing since I also extended the front of the model (the part that flexes with each click) by 0.5 mm, it's printing with two lines instead of one (on a 0.4mm nozzle), allowing it that extra bit of flex to where it wasn't a problem. I admittedly don't remember how much further I extended the triggers, but I think it was around 5mm, maayyybe 10mm. The additional flex might also be due to adding the fillets to the flexing area, thus adding a bit of strength there as well, but I'm no engineer. :) I'm admittedly unsure on how to post remixes to Maker World, but let me know if you'd like a copy of the .step file with my modifications!

@vsin

Replying to @gaudystead :

Remix button's the 3 vertical dots in the top right of the posting, go ahead if you'd like; like I said, I've got a version of long triggers that I benched, plus I'm a chamfer addict :P

Great model. Love optimum techs channel. This kit came to 32g Vs my Logitech G305 at 83g. it's a bit small to hold. May try the XL remix.

This is a great print with a great profile, printed with zero issues. I’ve been curious about the whole “ultralight” mouse thing but hesitant to pay some of the prices for something I’m not even sure I’ll enjoy using. looking forward to giving this a go and who knows, I might end up loving it. Thanks for sharing and allowing us to have a low cost entry point.

Absolutely no issues, everything comes together great and it's a great use for the kit!

Printed directly through the app on my A1 and came out very good. Thanks for the model :) Been an Optimum sub myself for ages and this really hits the spirit. Great work! Take my boost :) Only issue is with the hardware itself. Liftoff distance is SUPER low. Makes it barely usable.
