I love HKR Modular H2D Chute but I also have K2 Plus, so I made the K2 Plus slide to use the HKR Poop trays. See link below:
HKR MODULAR H2D POOP CHUTE - NO HARDWARE REQUIRED by Hiro Koiso Racing MakerWorld: Download Free 3D Models
This is just the slide only, see the HKR link above for the other items required.
Requires 5 - 15x3 magnets.
I designed this myself; I measured the tray to match up the fit. Under other files download is the Creality Slicer K2 Plus 3mf file.
The author marked this model as their own original creation.
