If you’ve ever spent ages fiddling with your printer’s settings, only for it to produce blobs of useless plastic, you should be suitably impressed with this 3D-printed lathe, built by Harrison Freedman while he was still at high school.
Impatient with the wait of sending robotics parts away to be machined, and with his school unwilling to let students loose on a full-size lathe, he did the sensible thing and made his own miniature one. It uses a 12 V DC motor, some aluminium framing, and 6mm stainless steel shafting, and cost around $200 to make.
