🛠️ The Ultimate Geek Drink Coaster
Level up your desk setup and protect your workstation in true maker style! Whether you’re a programmer fueling up on coffee, a hardware engineer sipping tea, or a gamer chugging energy drinks, this Circuit Board Coaster is the ultimate desk flex.

It is designed specifically for single-extruder setups to achieve a stunning, multi-colored look without needing an expensive MMU.

Obviously much easier on multi color CFS system

🌟 What's New? (Updated Today!)
Smoother, More Effective Design: Fully optimized paths for sharper traces and a cleaner top-surface layer finish.
Upgraded Holders: The downloadable files now include optimized holders for both 4-coaster and 6-coaster setups (perfect if you decide to add thick cork backing to your prints!).

🎨 The Single-Extruder Multi-Color Trick
You don't need a multi-material printer to make this pop. By using ****'s "Filament Change" script in Post-Processing, you can pause the print at a specific layer to swap colors manually.

Crucial Layer Change: If printing at a standard 0.2mm layer height, set your filament change command exactly at Layer 22.
🚀 Pro-Tip for Perfect Prints: Color changes can occasionally drop a messy blob right where the nozzle resumes. To combat this, I have included a tiny sacrificial file called 2colorwipedot.stl. Drop this onto your build plate alongside the coaster, and use ****'s preview mode to ensure the nozzle heads to the dot first right after the filament swap. Any initial oozing happens safely on the dot, keeping your circuit board absolutely flawless!

📦 What files are included?
Circuit_Board_Coaster.stl – The main event.
2colorwipedot.stl – Your secret weapon for clean color changes.
Circuit_Board_Coaster-Holder4.stl – Sleek storage for a stack of 4.
