Customizable telescope

It's not a real telescope (i.e. no lenses), but it has the telescope mechanism. The pieces won't detach from one another, and will lock into place when full extended. It's fun to play with.

I made two different designs. There's the screw, which is a nice effect, but is superfluous. So, I also made another design with a tab sticking out of each piece to keep everything in place when it's expanded. The tab is more stable when extended.

I've printed some fairly big ones, but they take a long time.

Have fun.
