Arduino controlled rotating tray designed with FreeCAD and arranged with CURA for 3D-printing

Model created with FreeCAD-0-17

This rotating table is designed to be mounted on the axis of a stepping motor NEMA17 having a
M5 diameter. The 3D-printer option is here ideal since it is a good means of having a perfect
centering of this hole to be inserted on the axis. The tray main dimensions are diameter 12 cm
thickness 3mm axis sleeve cylinder 20 mm.

Display-Workshop-Part design
Create a sketch, XY base plan. Should rotate around Z and XY must be the base plan which

countains the largest planar surface of the object.
Make the object precursor profile which must be revolved.
Exit sketching
Make the revolution and check the proposal and say OK.

The open with CURA
Adjust the parameters 1-line width = nozzle diameter etc..
Printing time = 3h30 can be reduced by using a larger nozzle diameter

Prototype of the electrified system

The schematic diagram is available here CP0097 and is due to Philippe Demerliac author of the CYROB channel. His excellent project has been reproduced exactly the same.
The rotation has 2 working modes. 1) first is the SPEED MODE whose speed can be adjusted with the knob rotation, the led is green and red if the adjustment is too much and 2) if the knob is pressed vertically the TRACK MODE is entered the the led is blue and any single rotation of the knob triggers a similar rotation of the tray. Return to SPEED is done by a new vertical press on the knob.

This rotating tray can be applied to video recording, 3D scanning, or any future idea...
The enclosure box has to be done with the sake of compacity and practical usability.
