3D PRINT STRONG locking bracelet

prusaprinters

<p>This is a simple variant of a locking bracelet I designed for the Engineer's Day Open House, February 28, 2015, at the University of Kentucky. The version handed-out from my lab had the UK logo on it, this one has the words "3D PRINT STRONG" on it... and strong it is! Despite printing in PLA just 2 layers thick, the tiny interlocked-3/4-circles can hold scary weights without unclasping: note the photo with the fish scale confirming it doesn't even come close to unclasping at 21 pounds of load.</p> <h3>Instructions</h3> <p>This is a very easy print, spiralized in 0.25mm PLA on a MakerGear M2, except for the fact that it might not like to stay attached to the bed. Printing it with a 3-strand brim helped a lot; it takes about 5 minutes to print and uses about 3g of PLA.</p> <p>This is a one-size-fits-most bracelet, so resizing shouldn't be needed.</p> <p>The first photo is just the 3D PRINT STRONG version in white. The second shows both the original UK version and this version. The third was a load test of a slightly bad print of the UK version -- even the bad print was able to withstand huge loads. I put the bracelet on a piece of wire rack, and even with my fish scale's hook creasing the bracelet, I couldn't break the clasp mechanism open. The photo shows the scale at just 21 pounds because I took the photo while pulling down on the scale, which is harder than it sounds. ;-)</p> <p>Incidentally, to unclasp: push the sides of the bracelet in a little and the rings will unhook. Easy.</p> Category: Bracelets
