I like Laura Kampf's Zippo bit safe idea. It's a small hack but a real nifty one. Kinda like how people put all sorts of things inside Altoid tins. And then she went ahead and released a .3fz and STL file for it. Nice!
All props go to Laura. Not my idea. Do check out her Youtube channel.
If you've got a Leatherman with a bit driver, definitely check out Cyclenerd's version too. It fits 6 double sided bits! and uses magnets for capture. Maybe I need to buy another Leatherman?
.3fz and .stl files are here: https://www.stepcraft-systems.com/en/products/q-series
Scroll down until you see it. The .3fz has a CAM solution already plugged in.
Immediately after printing one, I gave the design a handful of subtle tweaks.
- added a pair of grooves around the large flats to make it a bit easier to pull it out.
- recessed the bit holder by the hinge an additional 8mm so it would clear the close mech bracket.**
- recessed the other bit holders 1mm lower. Noticed that one of my fatter bits just nipped the cap.
- enlarged the hex bit holders from 6.6mm to 6.8mm so the bits would move more freely.
- I added a horizontal slot to accept a 3mm x 5mm x 20mm magnet I had lying around to capture and hold the bits.
- radiused the top and bottom of the insert so it would seat and close a little easier.
** To really make Laura's Zippo bit safe, you need to remove that. I couldn't compel myself to do it. :) I chickened out when I had the pliers in my hands. Obviously, this makes this socket harder to use.
