Peristaltic Pump Stand for Operant Chambers

thingiverse

The user should stand behind a peristaltic pump to deliver liquid reinforcement in the Operant Conditioning Chamber. First, inspect the Operant Conditioning Chamber at http://www.thingiverse.com/thing:1226076. It's suggested to use a layer height of 0.3 mm with a fill density of 20%. Support material is not required. To build this device, you'll need the following items: a 12 VDC peristaltic pump from adafruit.com/products/1150, four #4 x 1/2 in metal flat Phillips screws to attach the pump to the stand, and a 21-gauge needle taken from a 3 cc syringe. The plastic tip of the needle goes into the silicon tube on the pump end that will be attached to the water tray in the chamber. This ensures precise drops of water are produced each time the pump's DC motor operates. Print settings for this device are as follows: Printer brand - Robo 3D, Printer - R1 PLA Model, Rafts - doesn't matter, Supports - no, Resolution - 0.2 mm, Infill - 20%.
