3D printers build models in layers and you can see them if you look at a model closely. If you want a much smoother surface, you can achieve an injection mold-like quality with a little acetone.

Acetone is a powerful solvent that can actually break down acrylonitrile butadiene styrene (ABS), which is a plastic commonly used in 3D printing. And as Matthew Perks demonstrates in this video from his YouTube channel, you can use the vapors acetone gives off to smooth a model’s hard edges. To do it, you’ll need a tray, a tall glass, some acetone, and a small metal platform for your model to sit on. You’ll also need a small piece of cardboard and a paper towel.

Set the model and platform on your tray, then fold a paper towel into a loop and put it at the bottom of the glass. Wedge it in place with the cardboard piece, and pour a little acetone in the glass so the paper towel can absorb it. Now place the glass over the model and fill the bottom of the tray with a little water so the acetone vapors don’t seep out. After some time passes and your model starts to look shiny, just remove the glass and let the model dry.

I think we can all agree that dips are very important, and a good one is all about finding that perfect balance of flavors that keeps you coming back for more. Luckily, this creamy horseradish-packed dream from Epicurious has it all.

The video above tells the whole story, but all your doing here is mixing a bunch of tasty things together. Just grab a tub of full-fat Greek yogurt, a jar of prepared horseradish, and a couple of garlic cloves. Spoon in the horseradish, grate in the garlic, add salt, pepper, and red chili flakes (exact amounts can be found in the link below), and stir it all together. Dip potatoes in it. Dip vegetables in it. Dip chips in it. I think you get the idea.
