The Bearded Yell
Made by krunkosaurus, uploadedDescription
Cold cast using resin and iron powder using @markledford's print. End product was airbrushed black and then burnished with steel wool and a spoon. This is my first cold cast, and a challenging one. Thanks to the original artist for uploading! Details of my adventure here: http://imgur.com/a/Ro9C0

Happy to contribute back @bendansie!
I added a link at the bottom of the imgur.com link that lists all items needed and their associated cost. The other three tips I've learned are:
1) If the mold requires cutting to remove the print, cut in a zigzag pattern. It's easier for it to form a seal when making copies.
2) Consider lego enclosure: http://imgur.com/o7w73hD
3) The company Smooth-on makes great products. The silicon bit was super easy, the resin stuff was so complicated because the little catalyst dropper ratio. Someone mentioned Smooth-on makes their own resin. "The 300 works pretty awesomely and it's a 1:1 mixture for a and b." This would have helped a lot!
Let us know how it goes!
Awesome post, love the how to guide.
It's not every day the internet provides you with a tutorial for the process you wanted to try using the item you wanted to try it on...
I was reminded of cold casting the other day on a completely unrelated project and thought of giving it a go. Still need to make sure I have the right precautions and setup, but the supplies look like they are available locally here. (Also hoping to get a really big Zortax printed version soon. Nudges @LukeTansell...)
In all seriousness, this is why I share models. Thank you for sharing your experience with the cold cast process, leaving in the things that went wrong for others to learn from and for sharing the end result! Inspired to try and finish up another model this weekend to post, but we'll see how that actually pans out. :)
Awesome!
