I had an old Replicator 2 collecting dust. It always had extrusion issues so it sat.
This design fits the E3D Hemera (technically, I used the Trianglelab Matrix).
Hardware needed:
I reused the existing 5050 radial fan from the Rep2. I used a the new 40mm fan included with the Matrix.
No parts need supports. The MAINBODY has support material built in, for the rear 2 motor mount holes, and the radial fan area. Easily removed with pliers or cutters.
The author marked this model as their own original creation.
