Buckle Box, Printable In One Piece by anewsome May 1, 2013

Description

This is my second try at a one piece hinged box with latch. This latch is a little easier to operate than my box design I derived it from. For more information about this box, see the box it was derived from.

I like this latch design a lot. It locks the box closed very nicely and this version I printed as a test, has very nice tolerance at the hinge and at the latch. Now that the testing is over, I can design my real project.

UPDATE: v2 files now how a more tolerant latch. I realized that the tolerance for the latch was mistakenly coded to be half the tolerance of the hinge, since the hinge has slop tolerance for both the mail and female side. The latch should break free much easier on this version. Thanks everyone who printed it out or at least tried.

I'll have to bite for some.....I have their regular silver PLA and it's much more translucent.

I agree about the filament. Of the 10 rolls of filament I have, nothing prints as smooth as this one. I got it from matterhackers.com and it's the PRO filament. It's a couple bucks more than regular filament. Honestly, the difference in the quality of the print is so great, I don't know how they sell any regular filament. Go pro!

What plastic (brand/color) is your box printed in? Looks amazing.

I also just realized that the version of the STL and .scad file that are attached, use a latch size and tolerance that is a little too tight. The latch rod/hole combo should be bigger and the tolerance a hair looser. I think then you'll get a latch that doesn't break when you try and free it up. Also, make sure you work the latch free using the least amount of leverage possible. Don't try and break it free by grabbing the longest part of the latch and working it from there.

One last thing, make sure you're not printing too hot. I tried prints at 230 and they were all fused. Only when I drop to 220 do I get reliable prints where the hinge and latch both break free with no problems.

The box printed well, but the latch broke off. :-(

Same here. The hinge was fine but the latch broke -- twice. I even paused the print and tried cut the latch loose in the middle of printing it. I am going to try again with a little bit bigger hinge and scaling the box by 1.25.
Thanks for publishing the box! It is impressive that the hinge prints as a single print.

I know the feeling. Did the hinge break free? I tuned and tried my settings on 4 different boxes before I got it dialed in strong enough to print a latch that would not break. I print mine at 100% infill. A scaled up version would also be stronger. Thanks for giving it a try, and good luck!
