Another needle file handle

Couldn't find a needle file handle I was happy with, so I made one. The needle files from my local hardware store are 3mm (1/8") in diameter and so the handle is sized accordingly.

Features:

• Handle is designed to print horizontally, so the fingers on the collet flex instead of breaking.
• Beefy ½-13 UNC threads allow for a tight hold on the file
• Clamping at the front of the front of the tang to minimize flexing and vibration during use

The nut prints just fine vertically. I use a little bit of hand soap to lubricate the threads.

Recommend settings for printing the handle horizontally:

• Auto-generated supports: Yes
• Support only on build plate: Yes

Update (3/11/2024)

• Address a weak point in the nut
• Smaller, rounder handle
• Add tabs to make printing easier
