Stir bar dispenser - 24-well array
thingiverse
**Work in progress - not fully uploaded yet; had to remake some parts** Device to dispense micro stir bars into 24-well multiwell plate arrays containing glass shell vials. Fits glass shell vials with 8 mm in diameter; 9 mm spacings. Holes for stir bars are about 3.5 x 6 mm. This one uses a M2 screw (M2x16 in my case) and nut and an appropriate length and piece of compression spring is added. No supports except for the stir bar slide out (supports required for offset piece). Minimal stringing should occur if you have your printer tuned; otherwise they can easily be cleaned up; ensure all pieces are smooth.
