I have had a 3D printer as my disposal since 2018 and I have become well aware of how all components work. All that knowledge was acquired through many files (some worked and some didn't). The file I used for my school project was essentially a copy, paste of an older file I made when my grandpa asked for a phone stand. I couldn't find the old file so it's not a 1:1 comparison, but it's still something that 12-13 year old me thought of.
I stated with a cube (I'm using Tinkercad) and made it to the dimensions I wanted. From there I cut a rectangle to make the separate lip and tall back and I took a slanted one to the back to give it the look of not a full cube with a few missing parts. My original didn't have the cut down the middle of the back. That was initially meant to be a hole so the file would take less time and use less filament. Somehow I ended up making the hole big enough so a finger could fit through, now it can be used to help remove the phone from the stand.
After I put the file into MakerBot it was a simple case of exporting it to my flash drive and then putting the drive into the printer.
The final print has the dimensions of 4X , 3 1/8 Z and 2 1/4 Y inches and it holds a phone quite well. I do wish I added a bit more space between the small lip and the tall back because I wanted the phone to recline more but what can you do. Sadly there was a part where the MakerBot added baseplate fused to my print and I was forced to take some sandpaper to it. The result looked quite bad when upside down and it caused un levelness, meaning the stand rocks back and forth.
I didn't really learn much from this assignment other than I am competent in my abilities for 3D printing. I learned everything before and I know how to do everything effectively. I think the only thing that I learned was how to use MakerBot effectively because it was never the software I personally use.
