Ossum Lizard: 3d Printed Open Bolt Pump

The time has come to reveal my secret project to the world.

For the past 2 years I've been working on this marker; it's almost ready to get shooting!



In 2011 I discovered the Reprap project and figured I could print my own paintball gun.
Got the printer in early 2013 and started work.

First thing I did was remodel my old Sterling pump in Solidworks and print it out; to see if a 3d printed paintball gun would work/ not break/ etc.
It shot! at about 150 to 200fps or so. I was pleased.
It looked a bit like this:



After that I figured I needed a design for my own gun.
Came up with this:



This is an open bolt design, this way you can have a detend and never have to worry about rollouts or double feeding.

It features:
- Autococker barrel threads
- Sterling valve
- Tippmann 98 trigger assembly and detend
- Awesomeness
- Metal hammer and hammerguide (made by taz22, thanks Leon!)
- No autotrigger

I'm hoping to get this thing shooting soon; the valve is beeing drilled and tapped for air.

This is what it looks like in Solidworks:



And some more phone quality pictures:




Thanks for reading! It would be nice to get a kickstarter going someday when the gun is working properly; don't know when that will happen. I just got sick of keeping this project a secret

I accept positive and negative feedback.

That's some fantastic work there! Is it all plastic or do you have metal sleeves inside? Very sharp looking, I'd love to see a shooting vid!

Only the trigger assembly and detend from a 98. Valve from a sterling and the rest of the parts are custom.
