My inquiry proJect By Nathaniel Veit

For my Inquiry Project I wanted to learn how to design things that I could print with my new 3D printer, the Flash Forge Finder. But to do that I would need to first find a place where I could learn the ways of designing. That place was TinkerCAD.

Materials that I was going to need

• 3D Printer

• Filament for the 3D Printer

• Computer/ Laptop

• Program to use to design the fidget spinner

On TinkerCAD there were 6 tutorials in total that taught you the basic movements and placements along with tricks you would like to know like how to copy and paste and stuff.

Challenge #1- Learning to select and drag

For Challenge #1 I was to move the light brown casing on to the dark brown spiral staircase. This challenge was made to teach you how to do simple movements of objects.

Challenge #2- Learning to move around

Challenge #2 was to find out who was behind the curtain, which turned out to be Elvis, by moving around the curtain with your mouse. The point of this challenge was to show you how to manvuer around the build plate.

Challenge #3- Resizing objects

For this challenge, you had to take a cylinder shape and place it on the design pad, then you had to copy and paste it twice, and place both of them on either side with different heights. The point of this challenge was to show you how to copy and paste and change the height of objects.

Challenge #4- Making holes

This challenge I was to put a hole into the wrench so it would properly work as a wrench. The point of the challenge was to teach you how to group 2 different objects and make holes.

Challenge #5- Learning to copy and paste

Challenge #5 was to copy and paste letter and drag them onto the keychain to spell out "Katie", this taught me how to copy and paste more efficiently with control c and control v.

Challenge #6- Learning to resize and rotate

This last challenge was the biggest one of them all, I had to put all I learned from the past challenges and use them all together, I needed to place numbers on 3 of the die sides then I needed to modify the sizes of the numbers.

Now that I was done with the tutorial part of my project, it was time to start to design a thing that I wanted to make. But first I had to think of what I wanted to make first, so I decided on making a spinner.

After an hour or so I finally finished the base design of my spinner, and I was going to print it out to see if there were any errors with the design so far. I didn't want to make the whole thing only to find out it didn't work out in the end.

Once I finished printing it, I put the bearings in and tested it out. It worked great! But there were some thing I was going to have to change. First off, the size. It was a lot bulked than I expected so I was going to have to change that. Second off, I was going to have to fix the bearing holes. They were not holding the bearings as tightly as I would've wanted.

This is the design i figured out that fixed everything I thought was wrong with the last one. The bearing holes are fixed, and the bulkyness is fixed. Hopefully when I print it, it will be the right size.

I printed the design I made and I quickly found out that the holes were way to big, so I was going to have to redesign the holes to be the right size.

This time when I printed it, after I finish resizing the holes, I found out that the holes were too small. So I decided to get a knife and carve it out, then the bearings fit very snugly. It wasn't perfect, I was going to have to resize the holes (again), but I liked the look of it so far.

This time when I printed the spinner, it turned out great! I decided to scrap the old design and make something similar to it, but a lot smaller. The hole sizes were perfect, and I thought the size felt really good and it wasn't too big.

People that helped me

My dad and my brother were both a lot of help for me and my inquiry project. My dad gave me his laptop to use and my brother helped me along the way with errors that I made, and helped me fix them. Without them I don't think I would've gotten where I am now.

Steps I took to get where I am

• First, I had to figure out what I was going to design

• Second, I was also gonna have to find a good program I could use to design a fidget spinner

• Third, I was going to have to design a fidget spinner and print it

• Fourth, I had to perfect the fidget spinner design (which took a lot of time)

Obstacles I faced along the way

• Procrastination- I procrastinated a lot durning this project, and waited till the last minute for everything, including this presentation.

• The print not being accurate in size- another huge problem was my hole sizes being way too big or way too small. It was very hard to get it accurate so the bearings would fit in the hole, and it would end up being that I would have to cut the holes to be bigger.

• Not having too much access to my dads laptop- the only laptop I could use was my dads work laptop, but since it's his work laptop he needs to use it a lot and that prevents me from using it. Whenever I had it, I would need to work fast and that caused many little mistakes.

• Having to redesign the whole fidget spinner multiple times- Since TinkerCAD is not very accurate, the holes would always mess up in size and I would either have to cut the holes to be bigger or try again until the bearings would fit into the holes without me having to cut it.

Things I learned

In the end, I learned a lot of things like how to 3D design using TinkerCAD and that you have to be very accurate with sizes or else the end product could fail miserably. But the most important thing I think I learned, is that you have to be very patient sometimes to make something good, because if you rush, there's going to be a lot of mistakes.
