A container I made for the Elegoo Centauri Carbon with the intention to put purge lines or any other bed trash in between prints. Designed to sit beside the screen, it's dimensions are W 230mm x D 80mm x H 80mm. I also designed a holding hook that fits over the top edge and plugs snugly into the USB and keeps it held in place. There's a few mm of clearance between the top and the door so it shouldn't interfere with it opening or closing. This was designed with the factory feet. If you use the vibration dampening feet or a printed version of the feet the holder will likely not line up anymore and you'd need to adjust it.

Material: Shouldn't matter too much, I printed in Elegoo PLA+ and it's pretty solid, then again it's just a container to temporarily hold print trash till I can throw it away and keep my area neat.

Container:

Height - 0.2

Wall Loops - 2 (will have wall infill) or 3 (will be solid)

Sparse Infill Pattern - Rectilinear or Gyroid (I prefer Rectilinear for this print)

Supports - Optional, It printed fine for me without them but if you want to use them they'll auto generate on the Elegoo logo

Holder: 

Height - 0.2

Wall Loops - 3, will be solid for the most part except for where it hooks on the container.

Sparse Infill Pattern - Rectilinear or Gyroid (I prefer Rectilinear for this print)

Supports - Recommended, I used auto orient which places it upside down at a 45deg on the hook chamfer. It auto generates supports in a small ring around the hook, so they support it and also act as a brim. If your Support Z Distance settings are dialed in for your material it should easily pull right off it from the bed.
