Viable for Ender-3/Ender-3 Pro/Ender-3 V2/CR-10 Pro V2 3D printer.
There is also shipping insurance provided by Banggood for ~24c, but if you are paying via PayPal, it also works out.
You may be able to get a further discount from using the Banggood app? Honestly not entirely sure how this app works…
Is this a better option?
