4mm Hexa-Hex Bit Holder Collection 01

thingiverse

Our 4mm-bitted electric screwdrivers came with many, many bits, held in cylindrical tubes, which means a hassle when you want to use it, so we whipped up a trivial 6-bit holder that can be tiled (manually--there are no connectors in this version, although you could drill out a small hole for a magnet). Set includes a Wowstick driver stand, a six-bit hex holder, a two-bit half-holder, and filler triangles that make cutting a base a bit easier (e.g., only external cuts required). Now we wish we'd done magnets from the beginning, but it's still likely we'll just keep whamming these onto MDF or aluminum bases for some heft. It's like tinker toys for 4mm bits. The 4mm hex holes are fairly tight; printing on our MakerBot Method we get a good fit--you might need to tweak up or down a percent or two (or three?) depending on your printer's accuracy. We intentionally left the center of the hexagon empty so our fingers/thumbs have an easier time grabbing bits. We might tweak the hole chamfers (moar chamfoar) to make targeting bit return incrementally easier. We may do a version with built-in holes for tiny magnets, but honestly, we'd rather just slab them onto something heavy with glue :shrug: We glued ours onto a piece of 0.5" MDF for some weight: threw seven (center and one on each edge) on the MDF, marked the edges, and hacked off the corners with a miter saw. We'll probably also do a similar 3d-printed base with a magnet on the bottom of each Hexa-Hex matched to magnets in the base: this will keep things (re)movable, and make that satisfying _snickety-snick_ magnet sound. If you're wondering which screwdrivers we're using these for (affiliate links): * [Wowstick 1F+ 64-in-1 Electric Screwdriver](https://amzn.to/3bc4zDK) (Rechargeable, pricey, nice to use) * [General Tools 500 Precision Cordless Electric Screwdriver](https://amzn.to/35eeZib) (Two AA batteries, much cheaper--we got a small pile of these) * [SainSmart Motion Control Screwdriver](https://amzn.to/396aiYW) (No longer available, AFAWCT) * A couple others we can't find the links to now. Nutshell is that we have a pile of 4mm bits along with the normal pile of .25" bits. Note that our pile of 4mm bits showed a variance as much as 0.05mm, which makes a snug fit a bit hit-or-miss.
