We all know about the linear_extrude(...) function that turns 2d things into 3d things.

I sometimes have found myself wishing for a similar function which could make a more rounded, result.

Just to illustrate what I'm hoping to achieve, my dream solution would, given this 2d outline:

would give me something like the following:

I want to post my design on Printables but my scad file uses a threads library found here. Should I just add a comment above the "use" statement with a link on where to get the library?

I made this partly as an exercise in learning OpenSCAD, and partly as a convenient way of adding rails to designs for 3d printable nerf blasters.

There's several OpenSCAD Picatinny rail generators on printables, but I think mine has the most features. I may have gotten a bit carried away in terms of adding more and more options - so I'm calling this done, at least for now.

I'd be happy to hear suggestions for more features, though it might be a little while before I get around to implementing them.

I created a lib for designing cabinets. I'm not a woodworker, but I can design some for myself and I found this lib useful enough to share. So enjoy.

We're happy to announce that we were successfully able to initiate a BusKill lockscreen trigger using a 3D-printed BusKill prototype!

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.
