Pocket Box Cutter with Spring Mechanism

thingiverse

Pocket box cutter with spring mechanism, which pulls back the blade into the enclosure when you release the button. Fusion 360 file is available for editing. The tool is meant to be carried on a keychain inside a pocket, without ripping a hole into the pocket. I'm not responsible for accidents with your private parts however. Make sure you put it together properly, in the same order as it's shown in the photos with the numbers 1 to 6 Things you need: * Stanley blade (Dimensions: 61 x 19mm) * Spring from a ballpoint pen The models are not oriented properly. Make sure you rotate them as shown on the photo with the number 1 in it. Use rafts on all models except c6_slider.stl After printing, depending on your print quality, you may have to "run in" the slider in the enclosure, so it doesn't get stuck. There are spring clips for springs in 3 different sizes. Try out which one fits best. If in doubt, use the one for short springs. It should work with longer springs too, but the resistance of the spring mechanism will be higher, and the blade doesn't extend as far as with a spring clip for longer springs.
