I'm missing the ring from around my rear foglight, the car is an LS2 Monaro.

Has anyone got one to sell ??

I don't really want to get one from MF.

Has anyone ever made one on a 3D printer ? or a suitable replacement light that doesn't require the locking ring.

Sorry I know it's not much help but both aftermarket options I looked at when my light fell out need the locking ring (which thankfully didn't go south).

I ended up running a round multi-led light which IMO looks much better than the original, bit bodged in but holding up well after a year and 12k miles.

Same as someone did in this thread http://www.pistonheads.com/gassing/topic.asp?t=909...

Somebody did make some of these I can remember reading the thread with pics and that a few owners had them supplied buy the op . So keep searching piston heads for the thread it's out there somewhere. I think they were red plastic.

It my have been this thread I was thinking of

Monkfish list the part also £72

Give me the dimensions and I'll print you one out, but it's unlikely to be super pretty. You would want to acetone vapour, plastic prime and paint it, so the hassle and cost starts adding up.

Was wondering how you where getting on with your ring problem Andy, you don't fancy getting one turned up on a lathe ? in alloy perhaps and then a bit of paint and bob's your uncle.

Warm the calipers first...

Jeez...is this it? I can take a good stab at that...I'll charge a mere £71... tongue out

Is it just press-fit? Could really do with a fondle to back out some dimensions.

Yep, that's the badger..... I'm not sure if it push fits or locks on, perhaps someone could advise

Give me some dimensions (and ideally some photos) and I'll print out a few.

I can draw up something by measuring mine but I don't really want to disturb mine by taking it out so if someone can measure the hole in the bumper that it fits into and possibly the thickness of the bumper I should be able to work out the rest of the dimensions and draw a model.

Dimensions are ideal (i.e. not a solid model) because I'll have to fiddle them a bit. FDM printers are basically precise but not necessarily accurate...

OK so this is the best i can do without disassembling my car the 10mm depth is a guess but can be trimmed easily.
The internal diameter is oversize to the lamp as it is at an angle when on the bumper .
The 59mm outside of the return could do with checking against the hole in the bumper
Also I've drawn it with sharpe edges were the original has small radii but these could be finished by hand.

I can work with that smile

MonaroMad, did you keep your squashed ring? Looking very closely at the photo on monkfish's page I suspect it has a couple of small fingers to keep it in place.

Mk1 roughed out - there are a few things wrong with this, but you can sort of see it's doable. I printed it upside-down which gives a poorer finish, especially given building a 45' overhang is bad for FDMs...either I can print it the other way up (and the flange on the back will suffer) or relax the angle to 35-40'. That said, it's possibly good enough already with a bit of fine filler. I added some tabs to grab the bumper, but they're too stiff and probably all wrong anyway - I've no idea how thick the bumper is.

Looks good but like you say you need the hole size for the bumper which I guessed at 59mm and the thickness of the bumper to make the clips work correctly.

In the other thread I posted earlier it says the hole in the bumper is 60mm so the ring being 59 should be an easy fit .

I knocked out a mk2 earlier and found printing it the other way up didn't confer any real improvement in surface finish (and obviously required support and so more tidying). The options are (I suppose) acetone vapour or some clever plastic primer/fine filler to get it really tidy. Sanding may work to a point. I think I'm out of acetone or I'd have a play...suppose I could get some tomorrow.

The clips are crap so I'll delete them - I'm assuming you can come up with a way to affix the ring since it probably won't be a good friction fit (given the unverified dimension) - 3M pad or I'd be tempted to try just wrapping a bit of insulating tape around it to get a tight fit. I'll make a mk3 and put it in the post if you PM me details (both).

e: Samkia's definitely look nicer (as you'd expect)...I've not got any plastic stock to put on the lathe, but could be tempted.
