Compact Magnetic Bit Holder for EDC – BitBuddy

This sleek and lightweight multi-tool is designed with both style and durability in mind. 

It holds up to four standard 6.3mm or 4.0mm bits, making it a compact and practical addition to your everyday carry. The snap-fit closure is reinforced with two 4x2mm magnets for extra security, so it stays shut when you need it to. 

A third magnet is cleverly placed at the tip to hold the bit in place during use.

There’s also a built-in loop so you can easily attach it to your keychain and always have it within reach. 

Printing is a breeze, with minimal support needed — just enough to keep the screw housing clean and tidy. 

Assembly is quick: you’ll just need three 4x2mm magnets, a single M3x12mm socket head screw, and an M3 nut to secure everything in place.

To better suit different bit tolerances or accessibility preferences, the model comes in two versions: Tight, for a firmer grip on the bits, and Loose, for easier removal if your bits are slightly oversized.

For best results, it’s recommended to print with a stronger filament than standard PLA, such as PETG HF or similar, though it’s not strictly required.

Simple, solid, and super handy!
