Big Willy - 3D Model Request

[bRIBEGuy]

I am looking for a Big Willy.

I guess I should probably add some context here...

I'm a big fan of the Tamiya "Wild Willy" (and other similar) styles of drivers, and as many do, often try to incorporate them into some of my builds as drivers.  I have been tinkering with a 1/5 scale (technically probably closer to 1/4 scale...) rally car build for a while, and as I am currently painting the body, I am trying to figure out some options for an interior.  I would LOVE to do a Wild Willy driver here... but he would need to be HUGE.  The only route I see to make this a reality (or at least even a possibility) would be if someone out there in TC Land, has a digital 3-D model of the head or helmet (or full figure...) that could be scaled up and 3D printed.  I don't have the ability to do the printing myself, but I do have a couple of local connections I could reach out to.

So there you have it.  Any chance someone out there can help me out here?  Figured it was worth an ask...

Thanks!

On Thingiverse are two or three Wild Willy stl-files. I think it should be possible to scale them up.

It is, I’ve scaled one up and printed it a couple of years ago. The mesh I used needed some cleanup but it was a good 3d scan from thingiverse. 

Edit: found a pic. That’s scaled up on top of a juggernaut chassis.

I did actually find a couple there last night, thanks.

My issue right now, if I'm being honest, is that despite 20 years of drafting/CAD experience, I've never had any real exposure to 3D printing and STL files, and in fact, the software I use (Alibre) won't naively import STL.  I was hoping I could find a STEP file, figure out a way to scale it, and go from there.

That looks great @ad456!

Did you just scale it up is a slicer program?  Think that would be the better way to go for what I am thinking of?

I ran it through Blender 3D and filled a few gaps in the mesh as it was non-manifold(not sealed) and took the mesh detail down as it was crashing the slicer I used to use. That was about 3 years ago but I’m sure I’ll still have the file I did somewhere in my project folder. 

Scaling it in a slicer would work fine if the model is good though!
PrusaSlicer should give you warnings if there’s issues with the mesh(it’s what I currently use). Not sure about Cura as it only allows me to print spaghetti on my delta

PrusaSlicer also have a built in option to repair the model through Netfabb service, I've used it a few times with good results. Although it might get quite slow at detailed models.
