Topic: Total failure on gear print

Working off thingiverse http://www.thingiverse.com/thing:251004 model. Worm gear printed okay, but the main gear print was all messed up. not sure where things went wrong. I did not use supports. it almost looks like it printed gear teeth twice.

Any thoughts?

Did you print it with the fillet side on the teeth down as suggested by the creator? Since that would create a ramp it should build better than trying to print with the flat side down. As for that weird double thing, not sure. It looks to me sort of like a layer shift but then the inside bore should show it as well and it does not.

Printing since 2009 and still love it!

Re: Total failure on gear print

Going to print your method next. My initial print did not turn out. Inside lip that hold's gear in place did not develop.. Reprinted gear with supports and upgraded XYZware. Picture says a thousand words.

Carl,

What do you mean by fillet side down.

Look at the gear in the and you will notice on one side the teeth meet the hub at a 45 degree angle. On the other side they meet the hub with a slopped angle. That is the fillet side and that side should be printed down.

Re: Total failure on gear print

Is that the side of the gear that has the 360 inset guide that the gear rides on?

In your second picture in the opening post the side that is not on the box should be the side that is printed down. That should be the side that the print starts on.

Re: Total failure on gear print

When I measure all the parts I'm dead on with what tinkerCAD says regarding dimension. Some where along the line I'm about 2mm to high on the assembled model. See Image. The only thing I can think is that the inside depth is to high. I don't have a measurement on that. I printed the case with flat side up and used supports. I think that the support on the inside my have raised the gear bed up. Tried to remove as much of the support that I could. I didn't think it would print well without support. What is the best way to print the main case?

Re: Total failure on gear print

Quick note: I originally printed the case flat side down and had some funky results. See photo. When I imported the stl files the case was shown with flat side up. Didn't think it would word that way so I flipped it. Results were bad like i said. So I then printed it as it came into tinkercad, flat side up w/ supports. Might try to rotate it on its side? Any thoughts?

photo on left was printed as shown, pic on right was flipped 180 and printed with supports
