I've wanted to make this since I saw people making new pads and handles but I didn't actually expect to see one. I am going to make one with a metal bar and make a metal plate for the main clamping piece inside. Then this will be as strong as the plastic and the print.

Just wanted to comment on how nice this looks

I appreciate you dropping by!

I printed this and it doesn't seem to work that well. Squeezing the grip barely moves the shaft for me, there doesn't seem to be any grip. It also doesn't tighten down to actually grip anything. Any suggestions?

There is a particular direction the clamp bracket should be inserted. Also spring tension has a lot to do with how much clapping power it has. My versions clamp hard enough to bend the printed rod, which is why I will be creating a version with a metal rod.

Thanks! I'm wondering if it's just my 3d printer settings, the tolerances seem a little too sloppy to me. I also bought the spring kit listed from amazon but i'm not positive I used the right ones. The kit isn't the most organized. I'll try tweaking my clamp bracket to hold a little tighter.

Yea it is a little difficult to decipher which springs are which in that kit, but I've found the variety very useful in other projects. I'm also working on a ratcheting version that hopefully will be even more sturdy.

I was taking a look at your design. Maybe a dowel pin made from a hanger on the end would increase the clamping power quite a bit. If you upgraded to a metal shaft, the dowel pin would still be applicable.

Hoping to find time to create a version with metal shaft soon! Thanks for the input!

How does the shaft stay in the end piece? You'd think with enough clamping pressure, the end would pop right off.
And is the shaft a standard size that someone could buy a metal strip for instead from say Lowe's or Home Depot? That way I could make a clamp as long as I wanted to as long I got a long enough metal strip?

The side of the clamp solidly connected to the shaft has some super glue dripped into the shaft hole and pressed in. I do plan on making a second version soon with a metal shaft for more rigidity and strength.

What are the dimensions of the shaft? I have a piece of 1/2" metal strip and can mill it to size if the shaft is smaller and for the end piece and add a bolt and make it clamp/expander.

The openings for the rod to slide through are 12.3mm x 5.3mm with variation depending on the dimensional accuracy of your printer.
