You can use commonly available 3D modeling software to generate your own models to print. 3D modeling software will excel at detailed models and models with organic shapes. If you are modeling something structural, such as a support bracket, you likely want to use CAD software. What software you use is entirely up to you. Blender is the most commonly used and recommended 3D modeling software, and it is free and open source. Below you will find a video walking you through the basics of using Blender. Many such guides exist across the internet.
You should keep a few things in mind when making 3D models to print:
1) Level of detail matters- printers can only print fine detail to an extent. Make sure you aren't expecting more than the capabilities of the printer. Too fine a level of detail can cause print failures too.
2) Avoid enclosed spaces with no support structures- open cavities in the print will result in rattling sounds as trapped supports cannot be removed.
3) Avoid steep overhangs with no room for supports- structures with such features are more prone to failing.

Computer Aided Design (CAD) software excels at modeling structural parts or items. One of its main benefits is the ability to precisely place features using its accurate measuring system, as well as easily creating symmetrical features or curves. CAD software struggles to create freeform organic shapes, though it isn't impossible. If you are trying to create a model that is structure, symmetrical, or needs precise placement of features, you will likely have the best luck with CAD software, otherwise you might benefit from other 3D modeling software.
Which CAD software you use is a personal choice, as there are many on the market. Tinkercad is a commonly used web-based CAD software. Fusion 360 is another commonly used software that is downloadable for free for students and teachers. Just like when using a modeling software, there are some things to keep in mind while designing a model for 3D printing.
1) Level of detail matters- printers can only print fine detail to an extent. Make sure you aren't expecting more than the capabilities of the printer. Too fine a level of detail can cause print failures too.
2) Avoid enclosed spaces with no support structures- open cavities in the print will result in rattling sounds as trapped supports cannot be removed.
3) Avoid steep overhangs with no room for supports- structures with such features are more prone to failing.
4) When communicating with the printing lab about your design, make sure to note any areas that need to be stronger for your design to be functional. This will allow the print lab to make sure that section of your model gets printed with the correct strength.

Slicers are software that generate gcode from your model to tell the printer the correct layer structure and toolpath to generate the 3 dimensional print. There are many slicers available for use, but the ACS Makerspace primarily uses Bambu Lab's Bambu Studio. Below you will find a few videos to walk you through using Bambu Studio to create the best project you can.
