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. Revolution parts User tutorials and FreeCAD wiki New file and give it a name 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. Select the part and export the file in format .stl 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 ...
