Topic: Hinge points

Still waiting for a printer here but I was wondering if anyone has printed anything with a defined flexible area to create a hinge between 2 seperate parts on a model.
I assume ABS would be too brittle and crack, not sure though.
I was considering perhaps a slot that could have part of a cable tie laid in and then have printing continue over the top hopefully capturing the tie solidly.

Re: Hinge points

I saw some hinges on thingiverse, but not like what you're talking about... ABS would break for sure

Re: Hinge points

Re: Hinge points

Id like to try to make a chip bag sealer, as they have that one hinged plastic point. Would be a good test.

Re: Hinge points

I would think that might be do-able.

I know there are some flexible things that do work okay.

You might not get something that can bend 180 degrees, but some bend should work.

Re: Hinge points

Can't seem to post urls yet. But for a simple clip design that you might be able to use for a bag clip see thingverse thing:15371. For a more complex clip design see thingverse thing:5580.

Re: Hinge points

I have a hinge that worked surprisingly well, more of a traditional hinge design but it does the trick very nicely.  I left .025" dia clearance between pin and hole and had to use a nail file on the pin to make it a little more round, and an exacto on the hole to clean up the entrance a little but it snapped in nicely and works great.  I attached a picture from solidworks with one piece transparent hopefully it shows a little better.

Re: Hinge points

Nice, I'm sure that style of hinge will last a lot longer than flexing abs back and forth a bunch of times.

Re: Hinge points

I think if I had it to do over again I'd make them conical so they self center, and should make more of a gradual overhang for the doodle to print, meaning less cleanup.
