 This mechanic works well, it is a proof of concept but we have lot of small 3D pieces to print.

6.1) Structure

6.1.1) Standard mechanical pieces

Standard pieces for the structure can be purchased on the internet, here is the list:

• Profiled aluminum 40x4cm
• Worm screw 50cm, (diameter : 8mm)
• Ball bearings
• Steel rod 50cm, (diameter : 8mm)
• Worm (M4)

6.1.2) 3D pieces example

6.2) Head

6.2.1) Standard mechanical pieces

Standard pieces for the head can be purchased on the internet, here is the list:

• Worm chicago (5mm)
• Worm (M4)
• Tweeter 120 Watt minimum
• Strong glue (epoxy)
• Lacquer cutting diamond
• Spring

6.2.2) 3D pieces example

6.3) Stylus

This is the most expensive part, because we need a cutting “diamond”. It can be purchased on the internet for more than 100$. For a cost reduction, some people use Roland blades, around 5$ but it is not the same sound quality.
