Turntable for Airbrush, Painting, Modeling Photos Rotating, 608 or BB bearing

thingiverse

Update 8/4/2017: Updated top BB bearing and added new 608 bearing versions for top and base. The BB raceway tends to require some post-processing for silky smooth operation. 608 bearing versions are fully interchangeable with other section types. Top is further inspired by thingiverse.com/thing:2035825 with integrated hooks along the edge. A turntable that can be expanded as needed uses 6mm airsoft BB's (up to 42) as ball bearings for free rotation. 4.5mm BB's can also be used but aren't as effective. A 20mm M3.5 bolt, washer and nut with loctight secure the top and base so the bearings don't fall out. Turntable diameters are top: 108 mm (4.25") and top extended: 177 mm (7"). Mix and match pieces as needed but only top and base are required. Crossed toothpicks or cups in height extension and feet sections add ballast (lead buckshot in small baggies) for a more stable turntable but ballast isn't necessary with just one height extension and feet section. The threaded cup can also be used to secure the turntable to a platform if you don't want to drill holes for screws. Various diameter, location and orientation holes are available for plugs, toothpicks, wires, rods, etc. Additional tools used in painting include toothpicks, rubber bands, pieces of wire for elevation, handling and securing pieces for painting, thingiverse.com/thing:1669403, thingiverse.com/thing:2117261. To do: insert-able domed plugs, angled toothpick plugs, pcb clamp-like wing/thumb screw adjustable clamps, articulated arms thingiverse.com/thing:801279, toothpick crane arms thingiverse.com/thing:2111631. Redesign the threaded section connection and improve top 608 bearing stability (wide base structure/roller wheels).
