Slim Folding Utility Knife

2-part folding knife with no supports or brim necessary. Print in the orientation provided.

After printing the two parts just insert the blade sleeve part into the handle. the top side of the blade sleeve should be on the same side as the triangle design on the handle when inserted. Insert at 90 degrees to put the least strain on the handle. It will snap in place when fully inserted. Test the movement of the blade sleeve and ensure it snaps open and close securely. These parts aren't made to be taken apart, it may break if attempted.

To insert the blade, you slightly bend the blade sleeve to get the locking pins out of the way of the blade. Push the front-most part of the blade sleeve down while pulling up the two locking pins (its the kind of ‘n’ shaped thing). it should bend just enough for the two locking pins to be out of the way of the blade while inserting, then click in place once fully inserted. (see image)

It's not necessary, but to add a bit of stiffness to the hinge: insert 1.75mm filament into the hole in the middle of the hinge, cut off excess, and melt it into place using your printers nozzle. you could also extrude some filament at the same time to really secure it in place.

To properly grip the knife, place the bottom of the handle in your palm, grip the clip with your bottom 3 fingers, and place your thumb in the debossed oval area of the handle. there should be a clear path for the blade to travel away from your hand as it opens.

Left handed users can print both pieces mirrored for better ergonomics.

Print settings:

PLA, 0.2mm layer height, PETG and other common filaments should be fine.

no brim (the clip might peel up with poor bed adhesion, but most printers should be alright)

no supports

enable “bridge counterbore holes” in orcaslicer or similar slicers to prevent drooping bridges (it doesn't affect functionality so its not strictly necessary)

at least 4 wall loops for best strength in the clip.
