Stitching Awl assembly for nail
Description
This is a small awl for making small holes, using nail as a sharp tip. Nail is just put inside and the tool is screwed together. Safety cap for nail included. I made it because the commercially available awl in hobby market is too thick and dull. Printing time 1h, PLA, layer height 0.3mm, nozzle 0.4mm, Prusa I3 MK3. The screw uses metric M12x1.5 thread, higher pitch for simpler printing. Outer part (with inner thread) is scaled 1.04 in X and Y directions for better clearance, can be adjusted in slicer, but this settings works very well. The nail should be 1.9 - 2.3 mm in diameter to fit in reasonably well with head <5mm. The openscad customizable file is included. Size of the tool is fixed, but can be adjusted with reasonably small effort.
