The “Morpheus” is an easy to print bracket that bolts right onto the existing mounting holes on the Ender 3 V2 Neo's X carriage using M3x6 Socket Head Bolts. It has holes for M3 heat set inserts to allow attachment of any variety of custom toolheads, including the WIP “Morpheus” toolhead that this was designed for.
I've personally printed it on a Bambu Labs P1S with Red Bambu Labs PETG.
The author marked this model as their own original creation.
