Messograf Caliper Pen Grip

Let's face some cold hard facts. The Messograf caliper pen isn't especially practical. It's more of a graduation present for someone going off to architecture school or a technical institute. Nobody expects you to really use it. As a pen, it fares a bit better but here's the other cold hard fact. This damn thing is a pain to hold. I feel like I'm holding a small sword that hasn't been sharpened. Sure, you can get ergonomic grips for pens, but the Messograf has that miniature broadsword shape to it so a premade one isn't going to fit very well and you'll have to grip it unnaturally tight to make it work. Printed this twice at different infills. Best advice I can give is obviously the lower the infill the more rubbery grippy it's going to be. The first one was average infill about 60% and was a very snug fit needed both hands and a table to slip it on and off the first time. It got better but I'd say only go thick if you intend to do more writing than measuring. If you're going to switch between frequently I'd suggest either a lower infill or even scaling it up by a hair. I don't recommend making it hollow however unless you can put a horizontal layer in the middle of it it's likely to fall apart if you grip it too tightly.
