Zowie S1 Wireless Mod (G305)

These are the orientations that I print the pieces in. Remember to use supports on the rechargeable battery holder. Typically I use eSun PLA+ so I don't know about other filament types.

I've printed this on an Ender 3 and Prusa Mini. I print with pretty close to the supplied 0.2mm Standard profiles so I'm not going to post my full profiles, but I would enable "print thin walls". You will need to cut a lot off of your S1. I would assume that this is not reversible.

This mod requires soldering. You'll need to put on a 13mm encoder. I usually try to make these work with no soldering, but the scroll wheel is completely untenable at the stock height. I am not experienced enough to detail the steps to do so. My assumption is anyone that actually wants to go forth with this and is comfortable soldering on a new encoder will already know how to do so.

-There are likely multiple combinations of chargers and batteries that work. These are the ones I use. The battery matters less than the connector since they'll only vary in weight and battery life. If you get a different battery make sure it's 1.5v. Video demonstration of rechargeability:

There is a lot of cutting. I suggest going slow and cutting less, then cutting more if it doesn't close or fit.

I've also attached a photo of my first attempt. I mistakenly cut pieces I shouldn't have and mangled the mouse's look. Just be careful.

Be careful with the ends of the battery wires. You can tear them off in which case you'll have to resolder the connection.

If you're using the rechargeable battery then plug in the magnetic micro-usb charging tip. Orientation for the battery and their holders are shown in the photos. Unplug everything and put the battery into position. For the rechargeable battery you'll want to tape the connection to the open end. I also typically add a piece of tape around the holder reaching under the pcb. The holder is small and thin like this so it can fit in all of the mice I've made mods for. For example, if it were longer and fully surrounded the battery, it would run into the internal wall and not fit.

Here are the screws I used. Save the long Zowie screw at the back of the S1.

Note that M2 isn't screwed in and sits at an angle. Mine hasn't moved at all while closed but once you get a good position you can always tape it to make sure.

As far as the printed pieces and where to put them they're all illustrated here. The piece highlighted in yellow is to make the scroll wheel able to reach the switch so it actuates when you push it down. You neef this because the encoder is 3mm taller than stock.

This is the part with the most variance. Do the front first. The front should snugly slide up. I haven't had any issues with it moving on two mice, but if yours does then maybe throw a dab of glue or something and do the rechargeable battery solution. I've printed it on multiple printers and the fit has been fine for me though.

Make sure the bottom is aligned laterally and screw it in at the back. You probably don't need the side back screws, but I'd suggest using them.

Do not be surprised if you knock something out of place your first time doing this. Just remove the top, see if something looks moved, and try again.

If it won't close then you didn't cut enough, or something else is out of alignment or in the way.
