Ender 3 Pro Laser Tray

thingiverse

I got tired of cleaning tape residue off my print bed after using the laser engraver mounted on my Ender 3 Pro. So I designed this handy peg tray system to hold things in place for laser work on top of the print bed. The tray is split in 4 to be printed 1 at a time upside down. The "Guide" pieces then slide in the rectangular slots to make edge stops. My x0 is a little inside these guide slots on the left, so I just made a guide that was a couple mm wider on top to align print media with x0 at the edge guide. There's "feet on the bottom to elevate the tray above my bed clips. There are varying peg shapes/sizes that fit the 5mm holes on the tray to hold print media in place. All of these should be printed with the top side down to avoid any need for support. For more information on setting up the laser check out https://www.instructables.com/3D-Printer-Laser-Build/
