Tools Required
If you prefer not to print the parts yourself, you can purchase a set of fingers and palm—just send me an email.
Currently, I only provide print settings for the J1s. However, the Prusa XL with dual nozzles may also work.
The single-nozzle Bambus are not suitable, as the AMS cannot switch TPU. The dual-nozzle Bambu also struggles to print soft enough TPU.
