Toucan, a safety cutter

thingiverse

Just another safety cutter, moderately useful and moderately cute. The blunt side of the blade sticks out from the back of its head just enough to serve as a glass-breaking tool. It's meant to be printed in one single piece; you'll need a disposable cutter blade that's about 18 mm wide. Find the bigger ones. The insert is calibrated for a 3-unit piece, or the final piece at the end of the blade (that's the one I used). Print Settings: Printer Brand: RepRap Printer: Prusa I3 Rafts: No Supports: No Resolution: 0.3 Infill: 30% Notes: This is a bit different: 1) Coat the blade with hair spray. 2) Stop the print at 3.25 mm. 3) Place the blade into the inset. 4) Restart the print. To get a better look, you can skip top and bottom solid layers; this way, the fill pattern can be used to achieve a better grip. Try to put a solid layer in the middle to make it tougher.
