A poop bucket and chute worthy of the K2. BIG! The whole impetus for this was a big bucket and ease of getting the bucket out from behind the K2 i.e the chute itself not being in the way.

Some notes:

The 4 PTFE tube multiplexer that may be mounted on the back of the K2 needs to be moved, it is in the way of the sliding chute. It can be moved to and mounted on the back of a CFS, there are mounting holes available there for it. The original two PTFE tubes going to the multiplexer in a single CFS installation can be swapped due to the changing required lengths for each.

Each model in its STL are orientated according as to how I found they printed out the best. The bucket has a divider in its center that is easy to scribe with an Xacto knife and remove it. That divider is necessary to get a good print. Without it the long sides at about a quarter way up during printing start to flex and quality goes to H in a hand basket. At 0.3mm layer height print took ~15 hours on the K2.

The mount is printed such that no supports are needed for the surfaces that the chute slides on. The chute is printed upside down with 0.1mm layer height and massive supports to get good looking angled surfaces. When right side up without supports at 0.3mm layer height it was ugly but usable. At 0.1mm with the supports pictured it took 9 hours on the K2. I'm going to try one more print at 0.1mm layer height and less supports just to see.

When the parts are first printed the chute will probably not easily slide on the mount. I designed a snug fit. The mount needs to be smoothed, scrapped, mostly the 90 degree edges of its rails. When the extruder changes direction quickly/abruptly or maybe at retraction a little bulge can build up on those corners, those bulges need to be smoothed out.

Once the chute slides onto the mount you should be able to tell the high spots and work to smooth those. If I can I'll include a short video showing how easily the chute slides on the mount once cleaned up. Or you can... In the slicer increase the size of the chute model by say 1% or so to provide greater clearance. Keep in mind I have not tried this so that 1% is just a guess I have no idea what the number would be.

I've included the mp4 video showing how easily the chute slides on the mount disguised as a .txt file in the Instruction Files section. So remove the .txt on the end of the filename and you can watch it.
