How strong are these actually? Just wondering if they can be used as wood glue-up clamps or if the pressure needed will snap the screw as it appears to be the weakest link. Is the thread standard size so it can be replaced with a metal one if needed?

The clamp can hold a couple of kilos. Not sure if thats enought for glueing.
The thread isnt standart. It designed to be 3d printable.

Hi,

can you please check my shortarm pivot, it seems to be smaller than the rest, is this ok!? I double checked the size...

Very cool clamp, hhanks for sharing!

Greetings

Hi Tino,

i checked your photo, and you assembled it wrong. The shortarm needs the smaller jaw (jaw-shortarm.stl)

Thanks, didn`t noticed that there are two differene sizes, now it fits perfect. :)

Great design, thanks

I am trying to print this but none of the threaded things like the handle and screws fit into the threaded parts. What can I possibly be doing wrong?

did you calibrate your extruder? Please make sure it is not overextruding. Due to the tolerances (0,2mm) (not the thread, that has much more ) even a small amount of over extruding can leed to a not fit.

There's a bit of a trick to printing working screw threads with FDM machines, you usually have to scale the hole up by 2-3% or the screw down by the same amount to get a working fit strait off the bed.

Best advice ever.
Thank you so much :)

At the time I printed the threaded parts I was adjusting temps and extruder flow and somehow that made the parts smaller or they shrunk. I printed the threaded parts again at higher temp and extruder flow back to 100%. Everything fit but a little interior trimming was necessary for a few pieces to fit together. Was very hard to screw parts together I got blisters on my fingers doing it. But now it is all put together. Thank you for advice on adjusting sizes slightly. I will try that in the future.

Nice Design. Going to print one soon.

I can't want to print this. Great idea. Thanks for the STL's.
