This is a Xenomorph Pen/Stylus holder I designed as I wanted one for my Wacom and I'm a huge alien fan :)

V3 Update: XenoPenHolder_V3.stl

I fixed some issues:

The angle of the teeth is now higher which makes them look much better as the don't "drool" down due to lack of supports so they are much sharper and nicer looking. I brought some of the side pipes close to the body - With high speeds printing i had issues that made them break/snap during printing so it's now much sturdier. Added some minor details. V2 Update: Xeno_Pen_Holder_V2.stl

I was not fully satisfied with the jaw design in the original version so I basically redesigned it with the following changes:

The inside is now shaped like a pen so any pen/stylus should fit in nicely and smoother than in the original design. Made it look a bit more realistic and added a lot of details (File size is therefore bigger) Removed the holes - they look cool but it's not really how the jaw looks. I think this version looks better and works better - Print this one at 100%
