More Efficient Pepper/salt Grinder Assignment

Introduction: More Efficient Pepper/salt Grinder Assignment

Hello, everyone reading my first instructable! For the last couple of weeks, since lockdown began, everything has been crazy! There are now quite a few holes in the wall from me banging my head into it (no, only joking!), and everyone is just bored out of their skulls. So, that's when I saw about the Distance learning contest with tinkercad, and I thought, phew, this is perfect to keep everyone's minds off the stress of being stuck at home. However, due to a problem, I have entered this instructable into the 3d printed contest. This instructable is trying for the make it Grand prize, as it is a salt/pepper grinder with moving parts, and all my kids ever wanted for the last few months was a 3d printer. By the way, one of the kids mentioned this contest to his teacher and the teacher said that he would give the child an 'a' in the report, so fingers crossed for us. So that being said, time to get started!

Supplies

Tinkercad, a computer capable of running tinkercad, and a 3d printer (optional)

Step 1: First Idea:

This is the first idea that the children came up with. It uses gears to crush the salt/pepper, then the crushed items fall down into a hole then into a chute, where hopefully a container will catch it. We don't know if it would work as we don't have a 3d printer, and I will try to publish another instructable if we win (as we will get a 3d printer with the prize) and show everyone if any of the designs work. The picture shows what the mechanism looks like inside, and the funnel-like thing on top is where you put the pepper/salt, which is in the picture with the red cover on. I will make another few Instructables to show how the children made their ideas.

Step 2: Second Idea:

So this is the second idea that we came up with. It has a cam which is linked to a piston/crusher thing, and that's how it crushes the salt. Oh, and if any of the readers want files for 3d printing, just say in the comments.

Step 3: Third Idea:

So this is the third idea. as you might be able to see from the third picture, it works by spinning balls around and the balls gain inertia and then accelerate and transfer their kinetic energy... well, that's the theory. (I thought it up when I was writing this) So, if you do decide to 3d print any of these models, this one is the least likely to work.

Thank you for taking the time to read this instructable, and, well, what else is there to say? I will publish other Instructables that hopefully will make it into the tinkercad contest, showing how the children made their machines. Stay safe, stay home and goodbye.
