3D Printed Cue Stick Chalking Tool

I designed and 3D printed a handheld motorized tool that chalks cue sticks.

• motor
• button
• wires
• 9 volt battery
• cue chalk
• 9 volt battery clip
• Case

• 3D printer
• Soldering iron
• Hot glue gun
• Fusion 360

I started by designing the case in Fusion 360

• I put holes in the case for the wires, button, battery, and motor.
• I designed a button making a cylinder then filleting the top outside
• cut a square hole in that to clip into the button
• made a spinner with thin walls that bend and slightly wider top allowing a tight fit on the chalk
• added hole for 9 volt clip

I put everything inside the case. Glued clip into case. Soldered wires from the battery to the button to the motor.

here is a rendering of a smaller,faster,and stronger version of the cue chalker
