I wanted a dead simple top mount for my Sturdy Bunny v2 ERCF without using any 2020 extrusion. Taking inspiration from jeoje's Sturdy Handles I made two platforms that mount to the frame using a single M5 roll-in nut and M5x10 bolt. You'll need 4 3x4x5 M3 heat set inserts and some M3x14 bolts to attach the ERCF.
I've also included a set of mounts that inclines the ERCF back by 35 degrees mimicking the Prusa MMU2. On my personal setup I found that it eased some of the sharp turns in the PTFE tubing.
Print using standard Voron print settings, 40%. I've included the Fusion 360 file so you can customize and make improvements.
