Aquarium feeding ring with suction arm
A feeding ring stops flakes drifting into the filter intake and concentrates food where slow fish can find it. The ring is 80 mm in diameter with a 10 mm tall hollow rim 1.2 mm thick so it floats, joined by a 40 mm arm to a 20 mm cup that accepts a standard suction cup stem of 5 mm. A 1 mm fillet on the inner rim edge prevents food snagging, and PETG or PLA are both safe once rinsed.

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.
