This project adds several features to Ch4rlesB's Medusa Toolhead.
- New clip-in belt mount design
- Optional bottom support brace
- Added support for ebb36 toolhead board (keeps original support for umbilical and Hartk board)
- Lowered X endstop so that it activates against the Y carriage block (removes need for endstop flag)
- Strengthened zip tie slots
- Added right-side support arm
- Resized heat insert slots from 3.9D -> 3.8D

I'm not a fan of most toolhead belt mounting designs. I designed this solution to be:
- Light-weight
- Strong
- Semi-toolless
- Easy to assemble
Insert the belt into the cavity, and slide in a printable clip to hold it in place.

Installation tip: The two front clips sit between the belt and X gantry, and might be difficult to install if you have big fingers. I use a screwdriver or thin wrench to keep the clip aligned while sliding it into the cavity.
UNTESTED
The original toolhead seemed to have excessive Y wobble during fast printing. The fan duct provides some support, but the duct itself is cantilevered from the back and seemed to result in a "diving board" board effect.
This support block aims to reinforce the front of the toolhead and minimize any bouncing/wobbling.
The block is attached using two m3x35mm screws, so it does add some weight. More testing is needed to determine if it provides any real improvement.
I tried to keep a tidy f360 timeline on this project. With some exceptions, most features are contained in their own group and labeled accordingly. You should be able to delete/change most features without affecting the rest of the model.
Uses the same hardware from the original project, plus:
- 2x m3x35mm screws (optional - bottom support block)
- +2 heat inserts (bottom support block)
- +2 heat inserts (for ebb36 + hartk/umbilical support)
- Input shaper testing (with and without bottom support block)
- Add support for 1515 gantry
- Beta testing - any volunteers? 🙂
