The photo version is printed using ABS because it's just really tough, ready-to-go material that has excellent material properties. It can also be vapor smoothed for that "just out of the mould" look. It has to be printed around 240 C and an enclosure is advisable - or a draft shield. But ABS just feels good in the hand.
I've tested TPU flexible filament with the result being a strong, part that gives like it's made from heavy, almost inflexible rubber with the right fill %.
I invented this tool a couple of years back, but Covid kind side-tracked my thoughts about offering it for sale. But it IS just as easy to use as shown in video - only took a dozen or so prototypes to get the release button feel and feedback just right. I thought of sending samples out to those doing video reviews. The tool is something I suspect EVERY Seecamp owner would want once they see it in action, though, I don't know if there are subtle differences between the Milford production and Southwick, because it's designed to fit the Milford current production precisely.
