Stitching Awl assembly for nail

thingiverse

This is a compact awl designed for creating small holes, utilizing a nail as a finely sharpened tip. Simply insert the nail into the tool and screw it securely in place. A protective cap for the nail is included. I created this design because commercially available awls on the market are often too large and dull for hobbyist needs. Printing time: 1 hour, using PLA filament with a layer height of 0.3mm and a nozzle diameter of 0.4mm, printed on a Prusa i3 MK3 3D printer. The screw employed in this design features a metric M12x1.5 thread, offering a higher pitch for easier printing. The outer part of the tool, which includes the inner thread, has been scaled up by 1.04 times in both X and Y directions to provide improved clearance. This scaling can be adjusted in the slicer software if desired. For optimal performance, the nail should have a diameter ranging from 1.9mm to 2.3mm and a head no larger than 5mm to fit comfortably within the tool's dimensions. A customizable OpenSCAD file is included, allowing users to modify the design as needed. The size of this awl can be adjusted with moderate effort if desired.
