This is a remix from McMuffin77 excellent Arkham Horror Portal. I found his model pleasing to the eye, but way to much for the capabilities of my printer
I used his tentacles and resized them to be bigger and less prone to break off during handling. Also i re-positioned and turned them so they support each other and had angles more to the liking off my printer/filament. The base and back plate i had to redesign, but stayed close to the original.
However, this is still quite some feat for an fdm-type 3D-printer to print. It will put a lot of stress on the mechanics while printing, especially when you are using retracts. You have been warned, don't expect something super smooth.
Uploaded new Picture: Printed with 100micron layer height and DasFilament PLA without supports.
