This is a simple plug for the bottom-center/heated bed slot on the Flashforge Creator Max 3D Printer. This was modeled from a 2018 Printer but should fit other Creator Max Printers.

Not tested on the Creator Pro yet.

This plug can help retain heat when printing with high-temperature materials such as ABS but also serves as a basic debris plug so that plastic scraps don't fall into the mainboard housing. I wasn't happy with the fitment of others I've found so I quickly modeled this one that fits snug as a rug, but can still be removed if needed. If you want a tighter or looser fit, simply scale the model by 1-2% :) Happy Printing!
