3D Print.
Ender 5 S1 with Klipper on a Raspberry Pi, accelerometer-calibrated input shaper, ADXL345 resonance test on every print. Mostly functional parts, not art.
Ender 5 S1, stock hotend, BLTouch, Capricorn tube, PEI sheet, custom cable management.
Klipper on a Raspberry Pi 3B+. Input shaper: mzv x=53.4, 3hump_ei y=135.0. Pressure advance tuned per-filament.
3d-printer-control bot: start/stop, status snapshots, completion notifications. Because the printer is in the closet and the closet is far.
Mounts, brackets, cable clips, gear housings, sensor holders. If it can be 3D-printed and is smaller than my hand, I've probably printed it for a robot.
Phone stand, cable organizers, a few household brackets. No figurines, no vases, no "art".
A full first-layer test square on every spool change. A temperature tower on every new filament brand. An accelerometer resonance test on every Klipper update.
The default 500 mm/s² is a lie. Real printing speed at 1500 mm/s² with proper input shaping is faster and quieter than the default.
Stock hotend with Capricorn tube + good cooling = fine for PLA/PETG. ABS and engineering filaments need a hardened nozzle, which I haven't invested in yet.
The camera + crowsnest + a USB hub are noisy on the bus. Caused Klippy to crash twice. Solved: separate USB controller, or just turn off the camera when printing long jobs.
