The scale is important as it’s a mechanism I’m trying to make for a product. Ideally I need the entire assembly under .5” diameter in square stock tube. This is just a first version so I was trying to prove it worked before we try to determine manufacturing costs.

Like engineering wise I know how the assembly works. My difficulty is executing it at a small scale without 3D printing it. I considered trying to heat the material to manipulate it so it’s flared at both ends. I also considered adding material to the tubes on the inside and outside part to...

The design is right. I guess what I’m asking is if there are any techniques that I could use to make it actually work out of styrene tubing? At this small scale I wasn’t sure how to add material to the tube. Just get wider tubes and cut a strip of material and glue it flush to the inside and...

I’m adding a link to a video of how to make a telescoping assembly in Solidworks. I’m trying to make something that functions like this. The tubes would be turned upside down and nested into each other to be assembled. The outermost piece would then be fixed to a solid flat base that will hold...

So something kind of like this, but it will be attached to a base plate. So the bottom, widest tube would be fixed to a flat surface and there would be nothing above it. So what I need it to do is go from a collapsed state to an extended state without pulling apart. If I had like a small lip at...

Hi everyone, I am building a small prototype for a product I’m developing and could use some help. I’m using Evergreen’s Square Polystyrene tubing to create a telescopic assembly. My issue I’m running into is how to keep the assembly together without pulling the sections apart. I’ve been trying...
