Printing tpu will no longer be a problem with ender 3
I was inspired by ezr extruder

this extruder fits any bowden printer (soon I will make a direct version)

you can reuse some screws and bearing of the original extruder.
the gear I strongly recommend you to change it (the original one is bad and has very little grip)

Necessary material
1 m4x8 screw with relative nut
3 screws m3x16
1 nut m3

1 gear mk7 (you can use the original if you are not interested in flexible materials)

update 9/05
ho caricato una nuova versione del file stl "fe" che presentava un errore

Stampare tpu non sara' piu un problema con ender 3
Mi sono ispirato a ezr extruder

questo estrusore si adatta a qualsiasi stampante bowden ( presto ne faro' una versione direct)

potrete riusare alcune viti e cuscinetto dell'estrusore originale.
la gear vi consiglio caldamente di cambiarla ( quella originale e' pessima e ha pochissimo grip)

Materiale necessario
1 vite m4x8 con relativo dado
3 viti m3x16
1 dado m3

1 gear mk7(potete utilizzare l'originale se non vi interessano i materiali flessibili)
