3D Printed SS100 Clone

Post by reenact12321 » Mon Sep 27, 2021 9:50 am

Hi all,

I stumbled on the 2006 era APH guides last year during the peak of lockdown cabin fever and nostalgic digging through stuff from my childhood. Finally I decided to make an attempt at my own APH (Nothing like building a water gun in November in Wisconsin). I ran into some hitches, I attempted to make a piston out of 3/8" PVC (Expensive and hard to find, and ultimately too small) and a wooden dowel. I also used a pop bottle PVC adapter to allow a 20oz or 2 Liter bottle to be put in on top rather than a backpack hookup like on the OG APH. I think my tests with a 20oz just didn't offer enough volume.


This year I was gifted a 3d printer, and tinkered around with it before the hunk of PVC sitting in my closet came to mind, I printed a perfectly sized piston, o-ring grooves and all and it worked great. (the build still has other issues and probably would need to start over)


I decided to see how much I could design and build for my printer. Reservoirs, pressure tanks etc will still need to be made of tougher stuff, but body parts, trigger etc would be a nice change from stiff ball valves and the like.

So far I've designed a body and controls as well as the pump (1/2 PVC outer cylinder, a scaled down piston based on my testing with my old APH), and the "Barrel" (really a guide for the pump and a conduit for tubing just like the SS100) will be 1/2" pvc as well.


I need to tear apart the body design and add the reservoir and pressure tank, but I'm waiting on some 1/8" tubing and small fittings/check valves to mock up first.

My thought is a 1L bottle as a reservoir and 2" PVC unit on top.

If the 1/8" tubing is too constricting I will use it only for the final run so the trigger can crush it, and use stiffer, bigger 3/8 tubing to mock up a second draft.


Current iteration work is on the grip. I want to make sure my screw holes work with #4 self-tapping screws before I got further, because then I can use those at other points to assemble the body shell.

Welcome to WaterWar.net!

Nice work so far. I would definitely recommend making the parts under continuous pressure out of tougher materials. Fortunately for a SS 100 style blaster the components that are under pressure (reservoir, tubing, check valves) are readily available aside from the pump. You seem to have a good solution to that problem, though.

I've been interested in seeing more use of 3D printers in homemade water guns but I have no time to do so myself. A pinch trigger and more ergonomic design should be easy with 3D printing.

Keep us updated on your progress. :)

Yes! This is one of the most interesting projects I've seen on here in a while. I would recommend improving the grip, though, perhaps by using using a real pistol grip. I used one on my own homemades previously and it was a good choice. You can of course also 3D print one, which would fit with the rest of the gun, but I just wanted to note that a pre-fabricated option does exist here. You've put a ton of great work into this and I'd really love to see the results when it's done.

That's really cool project . It will be awesome to see it in action. But I would shy away from making the barrel out of 3D printed material since it will be acting as a guide for the pump handle and needs to be both smooth and strong. In my experience every Super Soaker 100 and 200 I owned as a kid failed at the barrel by cracking. I would also reinforce the barrel attachment point. If you are wanting similar capacity as the original the reservoir bump up capacity to at least 1.5 liters. I would also make the nozzle easy to screw off as the needle like nozzle of the original traps sand.

Finally, someone did it lol. There is massive potential here to modernize the hobby, though getting the last bits will require a lathe and perhaps injection molding. But a ton can already be done with FDM printing and even more with SLA.
