A few aluminium levelling nuts featuring silicon columns have popped up on Amazon as upgrades for the CR10 and Ender 3. Check out https://www.amazon.co.uk/gp/product/B0887TF2TW/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1. These parts fit the Geeetech line of printers very well, with one issue: Creality used M4 bolts while Geeetech uses M3. Chris Eilbeck designed this little adaptor for me and said it would be alright to share.
