You will need a soldering iron, a multi-color printer, and printer capable of printing soft TPE.

Printing:
Use a strong material. I use Nylon 6-66 (CoPA).
Use lots of walls for optimal strength (I use 5 or 6).
Use a very soft TPE for the base cushion (I use Ninjaflex).
You will need to make your own tension markings depending on the type of springs you use.

Parts:
Springs: This comes down to personal choice, depending on how much tension you use. Inner diameter should be > 6mm and outer < 10mm.
