Pin Vise

thingiverse

A pin vise for gripping small drills or other tools with a one-eighth inch shaft, designed for drilling, reaming, or filing tiny holes by hand. The grip and handle are merged into a single unit. A central hole within the jaws features parallel sides, resembling a collet, which securely holds tools with a one-eighth inch shaft. This setup outperforms fully adjustable chucks because it grasps the tool along its entire length, providing a firmer hold and greater resistance to slipping. The chuck can be tightened tightly without risking damage to the jaws. The cap is an optional feature that fits snugly over the handle's end (it clicks into place). As it freely spins, it makes turning the tool easier while holding it securely. A small drop of light machine oil inside the chuck facilitates smoother thread movement, and a small drop inside the cap enables effortless spinning. Be cautious not to get oil on the inner surfaces of the jaws. Print Settings Rafts: No Supports: No Resolution: 0.2mm Infill: Check notes for specific requirements Notes: I have successfully printed these pin vises in PLA at a layer height of 0.2mm. To ensure optimal performance, use 50% infill for the handle to provide sufficient strength to the jaws. The chuck can be printed with 25% infill, while the cap's infill setting is less critical due to its minimal size and structural importance.
