I'm going to have a crack at doing some brush guards. I'm reckoning that I should be able to do a printable multi-part set.
They won't be amazingly strong, but the point is to primarily deflect wind/small bits of shrapnel/bugs, not large lumps of foliage/landscape.
More later.

Moulds, jigs and lay-up tools are a far better use of 3D printing than making proper components.
You need SLS for that  |
Not a bad idea, but I don't have the means/space to work with fibreglass. I was intending to use printed parts for the framework, with lasercut plates to do the actual wind deflection; as I say, it's not for proper off-road use. I think the most 'hardcore' bike that this is likely to go on is either my SV or my OH's CBF125.
And yes, SLS would indeed be preferable, but FDM is the best I've got, so I'm going to thrash it to within an inch of its existence, for no reason other than 'because I can' 
If we ever get a second lasercutter at work, I'm tempted to try and coerce it into functioning as an SLS machine, but it's not exactly going to be world-class.

That's a damn fine looking geetar Pat. I've been toying with the idea of printing a ukelele for a couple of weeks now; I think when I've got the big printer built and running, I might just do that.
In other news, I've got the printing demonstration in an hour and a half, and I've just found out that for some reason, the printer is really, really slow when I'm running it from a mac. This is after spending an hour this morning getting it to even talk t the printer. So much for 'it just works'.

Check Thingiverse, Hackaday, Instructables or any other DIY geekery-style site; they're chock full of ideas and designs for them.
The design I'm going to likely go with will have a geared stepper motor to control the turntable, a pair of lasers from those cheapo laser levels, and a pair of webcams. If I were to try and scan larger objects, then I'd probably go with one of the Kinect designs instead, but I'd rather spend days building a thing than pay £50 for it, if I can

Well, remaining squarely in the 'stuff what I made out of bits I had' school of manufacturing, I present to you my latest effort: a replacement part for a set of Sony headphones.
The headphones that I'm repairing:

The (out of focus) broken bit I was presented with:
https://farm9.staticflickr.com/8216/8275348142_653f93ed25_z.jpg
The model what I done produced:

https://farm9.staticflickr.com/8344/8275364324_7a73303da3_z.jpg
Aaaand the code that made it happen:
| Code: | module arch()
{
difference()
{
cylinder(r=30,h=6,$fn=120);
cylinder(r=27.6,h=6,$fn=120);
rotate([0,0,15])translate([-30,-32,0])cube([60,35,6]);
}
}
module barrel()
{
translate([-5,29,0])cube([10,8,6]);
pinbarrel();
}
module pinbarrel()
{
difference()
{
union()
{
translate([-7.3,40,3])rotate([0,90,0])cylinder(r=6,h=14.6,$fn=60);
translate([-8.4,40,3])rotate([0,90,0])cylinder(r=4,h=16.8,$fn=60);
}
for(i=[40:50])
{
translate([0,40,3])rotate([0,i*2,0])cylinder(r=1.5,h=18,$fn=120,center=true);
}
}
}
module pin()
{
cylinder(r1=1.8,r2=1.6,h=3.7,$fn=60);
translate([0,0,-2.4])cylinder(r=3,h=2.4,$fn=60);
}
module pinmount()
{
rotate([0,90,15])translate([-3,3,-27.2])pin();
rotate([0,-90,15])translate([3,3,-27.2])pin();
}
module headphone()
{
arch();
barrel();
pinmount();
}
difference()
{
translate([0,0,6])rotate([0,180,0])headphone();
translate([-10,30,-6])cube([20,20,6]);
}

I dare say that this could be written much more efficiently, but I've spent a grand total of about 40 minutes on it, so polish doesn't even begin to enter into the discussion at this point.
I'm warming the printer up as I type this, so will hopefully have something to show before too long, although what with it having been offline for a couple of weeks, I may have to spend some time re-balancing the bed first.
:edit:
I need to re-scale the main arc of it a bit, but here's the first shot at a finished product:

It doesn't look quite as scabby as the picture suggests, though

Well, if you can't measure it up, send me the knackered ones. Use a pushbike speedo in the interim; they're a fiver from Tesco, or thereabouts.
The actual cost of the plastic itself is pretty low; it's the amount of time that it takes which costs. having said that, that's a pretty simple shape, although I'll probably end up doing it in a couple of pieces, and seal it all together.
