Chimera+ Aqua

thingiverse

I'm currently crafting my own HEVO, but I don't want the part cooling fan that comes with it. So I'm creating a custom Chimera mount with a three radial fan design, staying within the original dimensions of the extruder mount. Of course, this requires some innovative fan shroud design. Having a model of the Chimera+ really helps. While I designed my previous parts using Sketchup Make 2017, the Design of fan shrouds far exceeds Sketchup's capabilities. Working in metric dimensions seems to conflict with internal imperial calculations (my guess). I encountered too many facets and surfaces that vanished during saving or edges that got longer or shorter as Sketchup tried to adapt. Wasting countless hours trying to fix my design, I decided it was time to switch tools. After trying Freecad (more wasted hours), I settled on DesignSpark Mechanical. It may seem inferior at first compared to other tools, but so far, I've been able to design everything I wanted. As a training exercise, I designed the Chimera+ in DesignSpark, taking roughly half a day. I used the CAD drawing from the E3D Dozuki as a guide, but keep in mind that their plans are incomplete. So I had to make some educated guesses. Even if my design looks very detailed, it's not suitable for making a Chimera on a CNC machine. Outer dimensions and mounting holes should be accurate, though, allowing for designing mounts and/or fan shrouds. I've included all virtual file formats that DesignSpark can export to. Let's hope someone can make good use of this.
