I used an online CAD software called OnShape to do all my 3D modeling. Every prototype I made, I made their dimensions 1 inch each so that there is no trouble when it comes to equal dimensions or trying to enlarge it. The 3D modeling process was brutal at first because I didn't know where to start, and how I actually wanted this game to come out, but in the end I decided to go with a 3 level game: easy, medium, and hard. Reference to Solutions page for the pictures of those.
For each object there was a protruding piece, and a hole corresponding to each other in order to create a snapping mechanism.
Once I had an idea of how I wanted to 3D model each object, I decided to test print my cylinder. The first attempt was a complete fail since I forgot to dimension it correctly and made it way too small. However, after fixing it's dimensions, when I printed it on the first try, it worked amazingly! If I could polish my design for the cylinder, the only thing I would change is the whole size, since it's not completely strong enough, but for my second try, it was a very good.
Here's a video of me assembling the cylinder as an elder would. I also show how each of the parts have a hole and a stick that matches together and a 360 view of the finished assembly.
*Note: I used one hand to film and the other to assemble; hence why the video looked so close up.*
With the same thinking as my cylinder, I decided to print my cubes. During this point, I hadn't finished modeling my medium level objects, so decided to tackle something bigger. When I printed out my cubes, it was failure after failure. I printed the first three blocks and was amazed at how beautiful it turned out! They were semi large and each block fit well!
This is a picture of the initial cubes of my test print of my cubes. They look small in the picture, but in reality are slightly bigger. I had wanted it to be bigger, but still I was struggling with trying to find out how to dimension the cubes on the building plate on the software Slicer that I used to simulate my 3D printing of my 3D modeled objects.
Here's a video of me assembling the blocks as an elder would. I also show how each of the parts have a hole and a stick that matches together and a 360 view of the finished assembly.

But then when I decided to print my second row of blocks, the dimensions were completely off again. With that being said, it was smaller in size than the first print, and it obviously didn't fit together. I know where this problem is, and that's when I'm trying to resize my dimensions on Slicer, it keeps giving me different sizes than my original, and I still didn't learn how to fix that.
So then what I decided to do was to mass print at least nine blocks in one print so that I can get at least one whole base of the cube object as one dimension and then worry about the other rows later. It worked, but it became so hard to assemble it, even I couldn't do it without remembering where each piece would go.
For the future, I think I would want to make it into an easier object, make each prototype bigger in size, and have each prototype be a different color instead of all one same color. Unfortunately, with the pandemic constantly spreading, and the lack of resources, I could not finish all my prototypes, and finalizing all of them, but with what I have done and printed, this is what my prototype looks like.
