Razer Viper Mini 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. My slicers are PrusaSlicer and SuperSlic3r (which are essentially the same except SuperSlic3r deals with thin walls better imo). 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 bits off of your Viper Mini. I think it's technically reversible, but really you're chopping off quite a bit here and if this bothers you then this mod isn't for you.

-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:

Here are all of the parts laid out and labelled.

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

Edit: I've added four new photos with some minor cuts at the back. I've found that cutting it straight like I have pictured allows for an easier fit at the back.

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.

Screw in the PCB. I typically just do three screws and ignore the one by the battery holder.

I've integrated the switch holders into the baseplate now. There are no longer separate pieces for them. Simply screw them in to the baseplate.

Cut the splines off the bottom of the switches. I left them on the right switch in one of the pics to show how the switches won't sit with them on. Now plug in the rest of the connectors and slide the switch holders over the top of the switches. The little square indent indicates the backside. You can also tape them down if that helps keep them in place better. The pieces are very small and any variation in the prints will likely leave them loose or ill-fitted.

Push the side button PCB down and to the back. If you've got the updated side button switches it should work still, as I've measured them and they're fairly similar, but for any fit issues old or new, I would try adding some aluminum tape or something like that.

The DPI button goes on the Viper shell. Snap it into place.

You shouldn't need it but I've included a baseplate with slightly longer front clips.

This is the part with the most variance. Align it at the front by the clips and push down and forward to slot it into place. Now push down to lock the back into it's plastic slot. You may want to squeeze the sides in at the back, widest point as well. It should fit like this.

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.
