M8 Precision Rod holder - NEMA 17 stepper

thingiverse

This is a short attempt at creating a 2-in-1 precision rod holder that can use the NEMA 17 stepper motor. There are two possible placements of the motor, one of them needing the bracket to be used. In the linear actuator configuration, you simply use the bar holder on top of the NEMA 17, and then use your choice of clamp to secure a threaded rod to the motor shaft. In the belt configuration, you can use the provided bracket to attach the NEMA 17 to the back of the bar holder and run the belt through the hole. Check the pictures for more detailed info. Also, check the attached SKP file if you need to change the model. Print Settings Printer: Prusa i3 Graber Rafts: Yes Supports: Yes Resolution: 0.2 Infill: 100% Notes: Piece should be solid enough for most builds. Just to make sure it will hold, you can extrude the back of the bar holder even further (it's at 5mm thickness right now) to maybe 10mm.
