Bambu Lab A1 mini poop chute and waste bin
A chute and bin that catch the filament purge from a Bambu Lab A1 mini during colour changes so it does not pile up behind the machine. The chute clips over the A1 mini's rear purge outlet, which sits about 30 mm behind the bed at the left rear, with two 6 mm pegs and a 45 degree ramp that carries the poop 120 mm out to a removable 100 by 80 by 90 mm bin. Walls are 1.2 mm on the chute and 1.5 mm on the bin, with a 3 mm lip so the bin slides in and out one-handed. Print the chute on its back and the bin upright in PLA; no supports needed.

Example prompt
Model a purge chute 40 mm wide with 1.2 mm walls and 25 mm side rails, sloped 45 degrees over a 120 mm run, clipping on with two 6 mm pegs 30 mm apart, feeding a separate open bin 100 mm long, 80 mm wide and 90 mm tall with 1.5 mm walls and a 3 mm sliding lip.
Fit notes
The A1 and A1 mini place their purge point differently, and downloaded chutes clash with the AMS Lite tubing. In SpeakCAD you describe your printer and desk depth, preview the chute in the browser, lengthen the ramp in the chat, and download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
