printed rails, Interest thread

Is it possible to see the "square" rail ?

[need4reebs]

any pics? what has changed? what kind of testing has been done?

[captian pinky]

could you use a cut down rt sear pin and make those wing things smaller.

[BTAutoMag]

I have one of each and I will be extensively testing them. I can tell you that each rail Weighs about 1/2 oz

[ScottyBeans]

1/2 oz is crazy light. That's awesome.

If you've got a boner for threaded sear pins, you could possibly use thread inserts.

The simplest option is to undersize the hole and press-fit the sear pin in. It's just a 1/8" pin.

The un-fun part is the tolerances on the 3d printed hole. 3d printing smallish holes accurately and consistently can be kind of a pain.

So the in-between is to oversize part of the hole for an easily sourced bearing/bushing -- adapt 1/4" to 1/8". And just hold the sear pin in with e-clips. Yeah, you have e-clips showing, but... come on, you're rocking a plastic rail.

No wings, either case.

sorry printer is being aa brick right now, its a term for a dead 3D printer.
working with my guy in NY and MN to figure out what happened.

not if you have a good printer :P
I never have problems with holes.

also why would I change stuff like the sear pin area, I have no problems with it, if it works leave it

its just a straight channel. no zig zag like on am mm rails or emag rails

Mostly because the threaded-ness I think is overkill and needs wings. Making one-off's is one thing, but making a bunch is another. If your printer can do it reliably, that's great.

What's wrong with your printer?

oh the layers are laying wrong right now, talking to a buddy and he is helping me out with it, its just a g code issue, which I know nothing about. lol
so he is trying to help me.

when you say needs wings, what do you mean?

If you want help with your printer/ Gcode allow me to take a look at it. I have been quite successful with my printer.

it wasn't the g code.
derp, I had some things just misaligned, we think.

thankyou I will keep that in mind.
thankyou for the offer.

The fat parts in the rail. In your case, the big chunk surrounding the sear pin (I think).



Yeah one of the reasons I've held back on the 3d printers is I want one that has a built-in auto-level probe if it's FDM...
