Warning: Sanity Not Included

 

Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn!
(In his house, dead Cthulhu of R’lyeh waits dreaming.)

 

Are you prepared to unleash the madness upon your shelf? This bust of Cthulhu is not for the faint of heart. It's a print that'll drive you to the brink of sanity, but hey, who needs sleep anyway?

 

As befits the Great Old One of madness and chaos, this bust is a very challenging print. I've only tested on my corexy P1S, but I'm not sure how it will fare with other printers (bed slinger owners, please share your experiences).

 

Having your settings dialed in tight and your filament dry will help you achieve a print that's almost worthy of the Great Old One. While most support surface defects are on the backside, post-processing is crucial for making him look his best from all angles.

 

Supports: The Unsung Heroes

 

While supports are often seen as an annoyance, they are absolutely necessary on a gnarlged, tentacle-y print like this one. I've done my best to angle the print so that supports are minimized and mostly on the back-side of the print. But still, there are small features. Go slowly and carefully when removing supports. Don't just rip them off. Use side cutters/snippers and take your time. Lord Cthulhu demands care and respect! Iä! Iä! Cthulhu fhtagn!

 

I have faith in you, though. You can do it!

 

Scaling Up (and Down)

 

This bust stands at 100mm tall by 120mm wide (about 4" x 4.75"). Scale it up as big as you'd like, but scaling down isn't recommended.

 

Print Settings

• If you're using some other slicer and can't use my 3mf file, I recommend these settings (and are what I used):
• Strong tree supports, on build plate only, critical regions only. "Thin" and "default" consistently failed in my testing.
• Print upside down on his head, tilted back about 40 degrees to minimize the number of supports.
• Paint some extra supports around the tips of the tentacles and the back of the head.
• Use 3 perimeters for strength. This will help you not break off any delicate bits when removing supports.
• Slow everything down and take your time (Cthulhu isn't in a hurry. He's already waited this long.).
• Arachne walls.
• 15% gyroid infill

The stand prints separately, and requires no special considerations.

 

(P.S. If you manage to create a print that rivals the majesty of the original, please share your creation with me... or don't. I'll understand if the madness takes you.)
