Unfortunately, although apparently well produced, the cap does not fit my NCVT-3 tool. Whether this is a printing or a design issue I am unsure, but either way, as a first experience of 3d design/printing, this has been less than satisfactory.
I got what's in the order, but somewhere along the lines I clearly misclicked something. The vendor did right, but... I didn't get what I wanted.
That being said, the rack part is curved in a way I assume mounting will fix. Otherwise the quality is excellent.
