My models can be a challenge to print. This has succeeded repeatably on Bambu H2D and A1 printers, and that's all the guarantee I can give. You'll need a clean baseplate and a well-functioning machine. There will be layer lines and other artifacts, there's no orientation that can make every bit come out perfect.

This needs a lot of supports and you can't hurry taking them off. I use electronics pliers and nippers, mini longnose pliers, X-Acto knives, and a butane soldering torch.

This can be printed in one material. With 2 materials I've had good results using translucent Bambu PLA for the supports and any other kind of PLA for the parts. Most Bambu translucents have lower layer adhesion which makes them easier to remove. This works best if the part material is matte, glow or glitter, i.e. filaments with additives rather than plain PLA. I haven't seen Bambu's Support material work well with these.

I'm a longtime artist with 3D printing but rather new to doing it at home. I welcome tech tips as long as they're reality-based.
