Hey all,
Here is my remix on the Prusa CORE One MMU3 Community versionvon Prusa Guy and combine it with the incredible MMU3 / MMU2S 5 Spools auto rewinder adapter for (un)original Prusa drybox / Repboxvon Sanka.
I really like the MMU3 core one setup, but the spoolholders and the buffer are not working well for my purpose.
I am still in test mode, but I already run it for 60h+ and it works awesome.
Let me know if someone have a good idea to replace the aluminum profile with a full printed part. So then you can print everything and mount it with some screws.
Thanks to all designers of the inspiration and effort that went into the design.
