Cheap VDE Screwdriver to .25 hex

So I found the Wera Bitholder for Inbus, and super liked the idea of making my own blades for my VDE screwdriver... BUT I had a super cheap, not quite VDE screwdriver set from Aliexpress, and not a Wera, and even though they look similar they don't fit each other. So I modded the original to fit my screw driver, but I didn't have much use for a cut off 2.5mm hex (well I do, but I haven't cut one off yet to go in the blade), what I could really use is a 1/4" hex driver, and or 1/4" square drive socket nut driver. And that's how we end up here. I made the blade a 1/4" hex, and inserted a metal 1/4" hex to 1/4" square socket adapter (because they're cheap and strong).

I took my mod from https://www.thingiverse.com/thing:6550419, and added a short 1/4" hex extension from https://www.thingiverse.com/thing:1385071. Which caused two problems. 1), I felt the fit was too loose, so I tightened it up by 2%, and 2) the shape of the object left unwanted overhangs requiring a tonne of supports. So I tapered the shaft in the opposite direction to avoid as much supports as I could.

The result is not bad. I've started with 5 walls, and 55% AI infill. I printed it standing vertically. I enabled tree supports, and no rafts. This gave me a fair size footprint that stuck to the bed even at the highest of the z-axis.
