Purchase of spares

Can someone tell me how I order spares such as extruders including the ntc thermsters. Noticed the parts issue section is locked and not allowing any new posts. This is the reason why I am posting it here. Many thanks.

You can find a list of spare parts in this link.

You can contact a Velleman dealer to order them for you.

I buy most of the parts in China

Thank you for your replies. Will try to find a dealer in uk.
