Hobby Knife For X-acto No.11 Blades

thingiverse

This hobby knife uses X-acto brand No.11 blades (the most common and popular blade size). The knife handle has been modified from a round shape to an octagonal shape like a pencil which makes it easier to hold and also helps prevent the knife from rolling off a table or desk, which always results in the tip of the blade being damaged. Also included is a safety cap/cover. Instructions Print out each part vertically as shown and assemble. When installing the blade, make sure you have it as far down as it will go in the holder. This will keep the blade from moving around. Do not overtighten the knurled sleeve. The safety cap/cover might be a little tight at first, just keep forcing it over the knurled sleeve until it loosens up.
