Shelf support pin

thingiverse

Here's a custom pin for supporting your shelf, designed with versatility in mind. The ABS plastic I used should work seamlessly well, but other types of plastics can also be employed successfully. It's highly recommended that you opt for 100% infill for optimal structural integrity. The pin features diameters of 6.75mm and 10mm, while its length measures 26mm. If you need to make any adjustments, feel free to edit the Openscad source file accordingly.
