Hi Guilhem,
Thank you for your support of our Thunder printer. Our factory has stopped the Thunder printer, and the other parts have already been sold. We only have 0.4mm nozzle on our website, the 0.4mm is a normal size and can meet various printing requirements, here is the free model printing website: Thingiverse and Maker World, you can check it.
We also recommend that you join our 3d printing groups on FB: 3D Printer User Club for help and communicate the printing skills and knowledge with 3d printing creators.
If you need any help with printing, you can contact our tech support at this email:support@geeetech.com for help.
