Polymaker PETG Black 3D Printer Filament 1.75mm 1kg, High Speed PETG up to 300mm/s, High Strength New Formula, Excellent Layer Adhesion, Warp Free, Compatible with Most 3D Printers

I used this polymaker dark grey high speed petg for the AMS riser. It's super close to the X2D color. IMO the biggest difference is the finish of the printed parts being shiny vs the X2D being more matte.I could see a fiber-reinforced filament being potentially closer with the finish, but I don't like using those inside my home. Getting creative with having the PEI texture on visible areas would probably go a long way with the finish too.
