Remix of Peter Sassaman's design. Filled in outer space to match other gridfinity tool holders and added more clearance to the hole the side cutters fit in.
Perfect fit for CHP-170 cutters. This is a 4x3 holder, with a total height of about 25mm (2.5cm). Grid sizing is very accurate, and a perfect match to the base. Cutters are not held tightly, making them easy to pull in and out of the holder. Well designed.
Also works with those generic cutters with the blue handle you can get for a couple bucks on eBay, etc.
