I have a H&K U.S.P .45 replica airsoft gun. In all honesty it is good but it can't compete with any airsoft rifle or shotguns. It needs all the help it can get and when the going gets dark a flashlight is just what you need. A quick google search or some T.V watching will lewt you know that every cop has a flashlight mounted under the barrel of his/her trusty sidearm.This is an easy part to design and to learn new software, plus it''s under 3 inches so you can use it for a free instructables print. You could buy this part online, but it would probably be more expensive, If you could even find it. 
Will upload pics of finished part when I get it.

You will need:
An airsoft gun (as a reference for sizing) 
A micrometer or ruler, depends how precise you want to be. 
3D Design software. I used Autodesk Inventor  (free student version) but there are free alternatives like Google sketch up or Blender. 
Access to a 3D printer (or free instructables print) or cnc if you can. 
 A flashlight also for sizing reference. 
4 bolts and nuts (small)

Are you using inventor?

Yes

Yes
Do you know what 42 means.
The answer to Life, The Universe, and Everything. Do you know what the question is?
Yes I do.
The question is.
What is the meaning of life?
And the answer 42 is the alphanumerical sum of, “To Be”.
T is 20, 0 is 15, B is 2, and E is 5.

I like your mount.
it looks realy good.

Thanks, Ill post pics when it gets here. Do you like it enough to vote for it?
All ready did dude.
Have you thought about doing the same thing with a lazer pointer?
Joe
That sounds like a really cool idea actually. By the way, LASER stands for Light Amplification by Stimulation Emission of Radiation. As such, the "Z" is incorrect.

Just saying.
No, I don't have one at least not one powerful enough to do anything. So I don't know what the dimensions are. Same process probably, if the lazer pointer is cylindrical. Thanks for the vote

I wish it works well for you. It's great idea and with a bit of Autodesk engineering you can make a lot more out of it. I wanted to do a laser pointer for my gun, but I'm stuck with proper aim calibration. I think I'll go with 3 bolts and hemisphere way.

I am trying to add image where I think the holes should be. Just for the record :)

That would probably be better, but it's too late for me to change. Vary interested to see how you're laser pointer idea works. Please post a pic, (virtual or real).
I don't know that you will be able to calibrate the aim, my experience is that the BB's curve all over after the first few shots (and some of the co2 is gone)

I believe you will have a problem with 2 top bolts that are actually going THROUGH pistol accessory rail. You will have to bore two holes in your pistol to get it on. I hope you've spotted it before sending to print shop.
Zaphod Beetlebrox (author)  sjzurek2 years ago
I don't think so, the holes are just bellow the rail. I think I left enough room. We'll see in a few months when it arrives.
great idea! do you have a link for the flashlight?
I saw the same one in The Source (electronics not snowboard) at the front of the store.
Sorry I don't know were I got the flashlight, I've had it for a long time.
