I didn't like the design of the brass drive coupling provided. It has a 4mm hole for a motor with a 3mm driveshaft, Thats just too much 'slop' for me. I was told to center it so it doesn't wobble by using the setscrews, seems unpractical so I made a 3d printable version. It's exactly the same but the hole is now sized to slip nicely onto the 3mm motor shaft. All you need to do is Tap the 4mm threads for the setscrews. I've attached a zip file.
