When you want a couple copies of a thing, you can 3D print ’em. When you want a ton of them, you might consider making a mold. If those are the shoes you’re in, you should check out this video from [Robert Tolone] (embedded below). Or heck, just check out all of his videos.
Even just in this single video from a couple years back, there are a ton of tips that’ll help you when you’re trying to pour resin of just the right color into a silicone mold. Mostly, these boil down to testing everything out in small quantities before pouring it in bulk, because a lot changes along the way. And that’s where [Robert]’s experience shines through — he knows all of the trouble spots that you need to test for.
For instance? Color matching. Resin dyes are incredibly concentrated, so getting the right amount is tricky. Mixing the color at a high concentration first and then sub-diluting it slowly allows for more control. But even then, the dried product is significantly lighter than the mixture, so some experimentation is necessary. [Robert] sneaks up on just the right color of seafoam green and then pours some test batches. And then he pours it in the exact shape of the mold just to be sure.
That’s just one of the tips in this video, which is just the tip of the mold-casting iceberg. Pour yourself a coffee, settle down, and you’ll learn something for sure. If you’re into more technical parts and CNC machining, we still love the Guerilla Guide after all these years.
Much thank to [Zane] for tipping us off to this treasure trove.
I recently got recommended 1 of Roberts videos, and now I can’t stop watching them. I really enjoy them
You and I got caught in the same batch. By any chance did you also get recommended Huygens Optics or Eric Strebel?
Lucky you, somehow youtube thinks I have a thing for infected cow hoofs, apparently…
(same), it was about 3 months ago…
Did he star in the movie “UP”?

Color matching? Avoid needing to do it at all. A well washed and dried Gatorade or similar heavy plastic bottle is ideal for this. Fill it with the Part B of the resin and color it as desired, keeping in mind that it will lighten up when mixed with Part A.
Now you have enough resin that’s the same color to make a lot of castings. If you kept track of how much of the dyes or pigments you added (this is where dropper bottles are very nice) then you can easily re-create the color in a new batch by mixing the same number of drops into the same amount of resin, or close enough.
Be sure to mark the bottles as to what their contents is, keep out of reach of children (better yet, tell them what it is and that it’s not for drinking), and print labels with the color formula to put on them.
I feel like I’d appreciate this more if it had less cultural appropriation.
(That object being copied is a Māori tiki)
Your assumption that we cannot speak for ourselves is far more racist than anything this bloke has done.
If the Mauri are mad they will kill and eat him, then brag about it.
How is “white culture for white people only” different from “stop appropriating other cultures”? went it full circle now?
I thought we were past all that race stuff. But apparently not.
Isnt Cultural appopriation a good thing as more people get to know about it?
And whats wrong about using all the good things that people created?
Maybe we should call that “cultural appreciation” to change the undertone.
