3D Printed Belt Driven Stepper Slide

#28BYJ-48 Mechanical Actuator #6 Making mechanical actuators using the 28BYJ-48 stepper motor and mostly 3D printed parts is a lot of fun. The 28BYJ-48 is the motor that comes with most Arduino kits, and it's a good one - a 5v dc motor with a max rpm of 15 and capable of around 4 oz force/in of torque. You can get these motors with the driver for around $2 each. #Belt Driven Stepper Slide This linear bearing slide is driven by a 28BYJ-48 stepper motor and a TPU 3D printed GT-2 timing belt. The linear bearing uses standard .177 (4.5mm) caliber steel BB's and has adjustment screws for setting the preload. The drive pulley has sixteen teeth, and with the max rpm of the stepper motor being 15 rev per/min, the max speed of the actuator is 480mm per/min. The slide will move roughly 10 lbs of mass before the belt starts skipping or the motor stalls. ===================================================================== Required Components M3 Nut (10x) M3 SHCS x 10mm lg.
