The filament waste goes into the tower. Then gravity and a little luck will take care of the rest (Source: All3DP)

At All3DP, we’ve gotten our hands on quite a few 3D printers (shocking, right?). Among the many, many, many machines we’ve reviewed – and have been pleasantly surprised by, merely okay with, or somewhat disappointed by – Bambu Lab’s have stood out in a good way. You can read all about our thoughts on the 3D printers that have taken the market by storm in our reviews of the X1 Carbon, the P1P, the A1 Mini, the P1S, and the X1E.

If you’ve read anything about these machines and Bambu Lab’s Automatic Material System (AMS), you’ll know that you can get some spectacular multicolor prints. The downside of these high-quality creations? The amount of material that is wasted. Also known as purge or poop (we didn’t coin it), we’re hoping that Bambu Lab’s upcoming steps are directed toward a less-wasteful future. In the meantime, we’ve been wondering what to do with the colorful ringlets (besides recycling them whenever possible, of course).

Enter the Poop Tower Game by GlennovitS 3D.

What Is It?

Well, much like its name implies, it’s a 3D printed tower with a honeycomb pattern that fits 3D printed beams. Once everything’s set up, drop the waste in, and players must remove one beam at a time, until a poop drops out of the tower. The designer has also included a few more game options with different rules, in case you want more ideas.

Why do we love it? Well, we’ve got a bit of a competitive streak among our team, and it’s always nice to repurpose waste if it can’t be recycled. Plus, between the colorful poop, the possibility of having beams in different hues (check out Shazadi’s make on MakerWorld), and the contrasting shades that can be added to the walls and connectors, it can look really cool. And we’re also competitive, in case we haven’t mentioned it.

3D Printing Tips

We don’t have many suggestions to make because 3D printing was mostly a breeze. While the tower showed no issues at all, we had a first-layer problem with printing the 30-beams-plate. But the presliced 10-beam plate worked like a charm.

Of course, it might depend on your setup, but the designer listed two printing profiles: One is for an AMS setup, with multicolor parts printing together; another is meant for all the pieces to be printed individually so that you don’t need to worry about color changes throughout. So far, three makers have also shared their printing profiles in MakerWorld, with Moixo adding one for the A1 Mini with – allegedly – less waste.

We printed ours in the X1E with the AMS without changing any settings. It took us 11 hours to finish all the parts. To our amazement, everything could be printed without support structures, so pluck your prints off the plate and start building. The assembly itself can be done by a 3-year-old, as everything fits nicely together.

And then, we got busy ~~playing~~ testing the model.
