It's open edit now, so feel free to improve it.

This is a 3D-printed custom coaster designed to showcase school spirit and provide an affordable and personalized solution for protecting surfaces from moisture and stains. The coaster is designed with the Principia school logo and Class of 2023 (or any other class), making it a great gift or keepsake for students, alumni, and faculty.

The design is created using OpenSCAD, an open-source software for creating 3D models, and is an accessible and customizable solution. The coaster can be easily adapted to feature different school logos and class years, making it a versatile solution for a range of school-related events and occasions.

This OSAT project is appropriate because it fulfills the basic need for protecting surfaces and showcasing school pride. It is a low-cost solution that can be produced using open-source 3D printing technology, making it accessible to a wide range of users.

Overall, this 3D printed custom coaster is an improvement on existing designs, incorporating school branding and personalization while addressing common issues such as moisture and stain protection. Its simple and practical design makes it a valuable asset for anyone looking for an affordable and efficient solution for protecting surfaces while showing off their school spirit.

Bill of Materials

1. Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts

• Filament (any color of your choice)
• Open source CAD file for coaster design
• 3D printer (Jellybox or similar RepRap)
• Sandpaper (optional)

Tools needed

• 3D printer
• Sandpaper (optional).

Skills and knowledge needed

To create this 3D printed clip/peg project, you will need basic knowledge of 3D printing and access to a 3D printer. If you are new to 3D printing, you may find these resources helpful:

• Beginner's Guide to 3D Printing: Link
• 3D Printing Courses on Wikiversity: Https:3D Printing|Link

Technical Specifications and Assembly Instructions

1. To print the coaster, you will need to download the 3D model file and upload it to your 3D printer software. The file can be customized to any class or even change the logo before printing. The print time estimate is approximately 2 hours, depending on your printer's settings and speed. After printing, you can use sandpaper to smooth out any rough edges or bumps. The coaster is ready to use after printing and sanding.

Cost savings

• This 3D printed coaster project is a low-cost solution for creating personalized coasters with your school logo and class of 2023. The estimated cost of materials is approximately $0.50 per coaster, assuming a cost of $20 per kilogram of filament. This is significantly cheaper than purchasing custom coasters from a commercial supplier, which can cost upwards of $5 per coaster
