PIRANHAZ

thingiverse

Piranhas are incredibly small, fun, and easy prints that pack a punch for their size... when you print some, please post images of what your Piranhas are feeding on! At standard scale, Piranhas measure just 42mm long and 9mm high. They print quickly and should come off the build plate ready to chomp down and clip / peg things closed. They're fun, practical, and make great gifts. Piranhas can be scaled up (not down as that will cause internal clearances to reduce and the print to fuse). Print in your choice of color... and, being such a small print (approx. 6gm filament), you'll want to print lots! A word of caution: Some slicing apps and/or less advanced machines may struggle with the fine clearances and bridging required for Piranhas. However, they've been test printed approximately 100 times on several different machines with no issues other than a small amount of sticking / fusing that could be easily broken free. It's possible that some machines will find it challenging to print Piranhas with freely moving jaws. Piranhas work in a similar but not identical way as my popular Sharkz design... but they're half the size at standard scale. Great fun, small prints everyone will want one! Two .stl files have been provided: one for fun and the other for a key fob version. Please refer to the print instructions and images for additional information. Note: If you like this check out the rest of my fun and practical designs. Also check out my other similar designs: Bugz, Z-REX, Ratz, Woodpeckerz, Sharkz, Crocz, Eaglez, Catz, Scorpionz, Fish Fossilz, Snakez, Print Settings, Printer Brand: MakerBot, Printer: MakerBot Replicator, Rafts: Doesn't Matter, Supports: No, Resolution: 0.20mm / Standard, Infill: 2 Shells / 50% infill... helps with the jaw spring action, Notes: Raft is recommended but not essential. Do not use automated support as it could fuse the moving parts. This design requires fine clearances and good bridging capability. Prints really well in PLA on a well set up / accurate machine with a filament fan. Post-Printing, Get your Piranhas biting! As soon as Piranhas are removed from the build plate (with raft removed), they should be ready to chomp down. A moderate amount of pressure on the upper and lower fins may be required to break the jaws free... but it shouldn't be hard to do for well set up machines printing in PLA and with a filament fan. If the jaw / biting action is not smooth, a small amount of silicone spray on the moving parts can make a big difference. This won't be required in most cases. The jaws should bite without the need to apply a lubricant... but they will snap closed much faster with it applied.
