In order to save space in my shack, i design these parts in order to place de buffer just behind the printer.
Must be print with supports and with the hooks front of the hotbed.
No need to replace the Ptfe Tube but consider to use these High Transparency Ptfe Tube... it's a better improvement to see clearly who is where inside the tubes
10 Meters are enought for replacing the 5 tubes to the MMU and the entry tube to the buffer.
Please like and post your makes.
Happy printing !
