Bob's Plumb: The Ultimate Tool for Unleashing Your Inner Hypnotist. Amaze Friends and Family with Your Mind-Bending Powers of Persuasion. Requires: * 3 M3 10mm long screws * 1 long piece of string (Steal it from your window blinds, but don't tell Mum, the Wife, Granny, or the Aliens Living in the Attic) * X some heavy stuff to add weight Print Settings: Printer Brand: RepRap Printer Model: Mendel90 Rafts: No Resolution: 0.25mm Infill: 25% Notes: You may need supports for the cutouts in the cone bit where the screws slot in. I barely managed to print it without supports, but it was a close call. The Aftermath: 1. Thread string through hole and tie knot. 2. Insert screws into top piece and screw them in (but not all the way yet). 3. Add heavy stuff inside the cone bit. Use marbles, sand, or lead fishing sinkers to weigh it down. 4. Place top inside cone bit, twist to lock, and snug up the screws so it doesn't accidentally come undone in your toolbox and unleash chaos (unless you used dogs of war, then you'll just end up with marbles or sand in your box).
