Lot of 2-Pack Fix-up Projects Elegoo Neptune Series FDM 3D printers

Type: 3D Printers

The listing pictures are for reference. This reflects the AVERAGE condition of defected and damaged units - we will pick 2 units from the lot with damage and defects that compliments each other (as donor/donee units) so that 1x fully functional unit is 100% guaranteed (or ANY parts are on us). This is a great project for doers that enjoy the learning and fix-up process. 

For example (as shown in the pictures)
Unit 1 has bad hotend, U frame, very filthy

Unit 2 has bad mainboard, PSU with cleaner cosmetics
They can compliment each other.
