I printed the magnet backs on a resin printer for speed. The magnets could optionally be glued in place without the backs using hotmelt glue or similar although it may not be as secure.</p><p>Make sure that the magnets are the correct way round when installing, I made all orange parts one polarity and all blue the oposite polarity.</p><p>The backs were then bolted together with springs to allow plenty of movement and flexibility.</p><p>The total cost I would estimate to be around £80 mainly due to the cost of the magnets.</p><p>&nbsp;</p><p>Links to materials:-</p><p>Springs <a href="https://smile.amazon.co.uk/gp/product/B076LWW73C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&amp;psc=1">https://smile.amazon.co.uk/gp/product/B076LWW73C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&amp;psc=1</a></p><p>Magnets <a href="https://www.ebay.co.uk/itm/372841535335?var=641728318720">https://www.ebay.co.uk/itm/372841535335?var=641728318720</a></p><p>&nbsp;</p><p>&nbsp;</p>
