Review: I purchased this to replace the broken plastic extruder on my CR-10 and was essentially just looking to have the machine back in action again. This arrived complete with a number of accessory parts including a much stronger bracket than that which was originally supplied. The pieces went together well and were an exact fit for the machine. I hadn't particularly purchased this as an upgrade but the supplied parts - especially the sharper 'cog' have really made the machine feel like new. This has given my prints a real quality boost which was unexpected and I'd certainly underestimated the difference that this would make. This is a really good kit at a very good price. Buy one.

*by A***O on 25 April 2021*

L'ho comprato per aggiornare il mio clone di prusa. Stó montando un estrusore tipo bowden con hotend V6; usato con il motore originale, facilissimo da montare, le istruzioni sono delle foto passo passo... quindi impossibile sbagliare. È tutto in alluminio, robusto e veramente ben lavorato e rifinito. Per il prezzo pagato e la velocità con cui l'ho ricevuto credo di aver pagato il giusto. Consigliatissimo come ricambio o come ho fatto io per upgrade. Comprato dal venditore Redrex3d. Spero di essere stato utile.
