These are simple caps that pop onto the top of hex drivers so that they can be identified from above.

I printed the example using an AMS however you could either do a color change pause or do them all in one single color.  They are designed to be printed face down (the side with text on the build plate).

I have made the following sizes.  Let me know if you'd like additional.

0.9mm

1.27mm

1.3mm

1.5mm

2.0mm

2.5mm

3.0mm

These pair great with the hex driver holder I also made.
