Quick Change Hex Bit Holder

Updated with a link to the Onshape document and some details that make it super easy to customize!

Why I made this:

• Got tired of my bits being jumbled up in a clamshell box

• Wanted to 3D print an organizer

• I wanted to print it in PLA because that's what I have multiple colors of for labeling

Why this is cool:

• There's an integrated flexure that keeps your bits retained without a friction fit or magnets

• The flexure is (nominally) not under load when in use, so it shouldn't creep over time - yay PLA!

• I'm also sharing the STEP of the "module" so you can go nuts remixing it

Additional notes:

• No supports needed

• Make sure you have enough perimeters that the flexure is all perimeters. It's a pretty thin flexure, so it might  be fine with just 2 perimeters - I'm only calling this out in case you are going wacky with your extrusion width :)

• The module is meant to be integrated into other designs! Go wild!

• I also uploaded my 10 bit labeled holder complete with bit of a shelf extension so that the holder doesn't wobble too much. 

How to make your own:

• Here's a link to the Onshape document so that you can make a copy and make the labeled holder of your dreams!

• All you need to do is enter a comma separated list of your bit labels. Don't separate the labels with spaces or anything else.

• There's a bit of custom FeatureScript (thanks, Claude) that parses this string and figures out how many bits you're using.

• Thanks also to Joshua Newth's "Text" FeatureScript that makes text patterning more possible!

• The rest of the CAD is built around patterning that will scale based on what you've entered!

• The part name will auto update to name the file with an indicator of how many bits are being held as well as what those bits are.

• I bet it'll break for <3 bits, but oh well.

• Yup, the CAD is ugly as hell. Done is better than perfect, after all :)
