Hello,
I was inspired by some simple commercial 2 axis camera gimbal to create my own, fully transparent in acrylic. For those who are interest I share the SVG file I drew to have the parts laser cut. See attachment below.
The pictures below show different views:
You can download the SVG file here : gimbal1.zip
Edit : other dowload link for those who have problem with first one : gimbal1-alt%20svg%20format.zip
And a PDF version : gimbal1.pdf

Michael, thx, glad it helps. A suggestion for improvement would be to use metal gear servos. Indeed as you see in this design, one servo is attached to the first one only by its servo gear. With plastic gear you might have a little wobble.
excellent. thanks for the idea/inspiration. i'm going to start on a similar design right now. using wood as i have plenty on-hand.
@Gary, I've added a pdf version in the post. Hope this works this time.
@Gary: This design is made to use a small servo ; I use the HXT900 from Hextronik. For the file , did you first unzip the downloaded file ? I will try adding a second link in the blog post with another file format
Agree, ABS would be a better material, but in the german factory where I order the laser cut, they do not offer the choice of this material.
@Gary : nice these servos. Do they have 9g servos (I do not want big monsters) ?
Nice!
I highly recommmend using ABS plastic sheets instead of acrylic. It's way stronger, doesn't crack easily.
You can get the sheets from servocity.com
Really nice design Hugues.
Those servos might be a little jerky though, on our mounts we've gone to metal gear digital to take out the jerk associated with the middle dead zone for stabilizing.
My friend Oliver is going to try doing this using these servo bearing plates from Servo City: http://www.servocity.com/html/servoblocks.html
It looks like you could just put 2 of them together to do pretty the same thing and they have an intermediate support bearing.
I don't have a point.. I am mearly suggesting adding another axis.. his title roll/tilt is correct. But not very may three axis gimbals out there ,. and the ones that do exist are pricy.
This design does not give you a true pan, just tilt and rotation.
cool.. you should add another axis and have a three axis gimbal. Which I think you could do pretty easily if you flip over the top servo and then mounted the pan servo to that.
