    The Lexus badge!

    Apologies to those that think we are "a bit strange" and should maybe go an have a lay down and keep taking the pills, but the Lexus engine has reappeared again. In a Gardner Douglas this time (see cars for sale, part built). It's not mine and I don't know the seller so this is not a plug to drum up sales, mind you if I had some spare cash (I don't) I would be knocking on the door of the seller for a look.

    Anyway I digress, for the Lexus users among us, the idea of a Lexus badge popped up again. It was discussed a while ago, well we kind of hijacked a thread for a while, and a few good ideas were "knocked" around. I've never really forgotten the idea and due to the fact it was mentioned again and the Lexus label just happened to fall off the engine a while back I had another go at a design. Just so everyone knows, art is not my thing, I've nicked a picture from google and sort of made it into what I was after. I have absolutely no idea how to make something like this and was hoping the 3D printer fraternity might have some input (please). I don't know if making this for the engine is the best idea, too much heat ect but it might be an idea for the front grill, if you have one, or the sides where the usual Cobra badges go.

    So over to "you", as said art is not my thing, if anyone can improve on this please do and if anyone can let me know a reasonably cheap way of making it I'm all ears.

    If you are OK with 'flat' then low volume laser cutting can be done fairly inexpensively - as an example, I think it cost me £60 (materials included) to have a set of footwell panels laser cut out of aluminium sheet as a one-off job with me supplying the DXF files.

    If you want contoured - 3D printed and then sanded & painted.. maybe a mash-up of https://www.thingiverse.com/thing:2358965 and https://www.thingiverse.com/thing:3470955 (apologies, Thingiverse is the slowest website in the known universe .. and that's when it works )

    All of the above! Way beyond my skill set in one reply!

    This could be fun and I'm guessing not as cheap as I thought.

    Here's what you get for five minutes of tinkering with existing designs - I'm no artist so the snake from scratch might be beyond me

    Any way of flipping the snake so it faces the other way, have the body following the "L" a bit more? It might make it look like the snake is sort of growing out of the Lexus part. Not sure if that makes sense.

    I got the Ender 3 Pro for £180 and I'm happy with it, though results (probably on most printers) depend on some trial and error and a learning curve as you start to understand how they work and that changing one setting can affect others. Fortunately, I like that kind of thing.

    If you want to print metal, though, I think you're talking a price that's on a whole different level.

    I use blender and cura to design my own items, though, and prefer functional items, from bathroom shower door hinge replacements to fake pusher fans for the Sumo (if you can call those functional).

    Well first you have to decide whether you want to print via FDM or SLA, and from there what kind of materials you'll want to print and from there .. or, buy yourself a cheap FDM printer and start playing

    I have an Anycubic Chiron, one of the bigger build volume printers (400x400x450mm) rather than the usual 220x220x250 (Ender 3 Pro, Prusa i3 etc) but that does make the machine huge and slower (it's harder to accelerate and stop the massive print bed without introducing wobble into the prints).

    Prusa i3 Mk3 is probably known as the 'best' hobby printer - but expensive.
    Ender 3, CR10s etc are Prusa clones IIRC, and are excellent value for money with minimal 'tweaking' needed
    Chinese crap is generally, er, crap. You can make it good but you'll spend all your time printing upgrades
    Anycubic are the best of the Chinese clones and actually generally quite good with a few small tweaks.

    As skinnymathew says, there's a huge learning curve to all the settings and things you need to tweak and understand to get good prints! But there are a lot of good online resources to help you.

    That's all FDM printing or, basically, squirting molten plastic down in layers. The prints have an obvious 'look' as you can see the layers (which can be smaller or larger depending on your printer and needs - larger is faster, smaller is a better finish). Mostly you can print in PLA (good, robust, slightly brittle, easy to print), PETG (good, robust, less brittle, harder to print), ABS (hard to print, extremely strong but requires a heated enclosure for best results), ASA (in between PETG and ABS), TPU (flexible thermoplastic - kinda rubbery - and meant to be a sod to print, I haven't tried).

    If you go for SLA then the print emerges from the toxic goo - I'm not kidding, literally that's how they work. Rather than squiring down molten plastic they use light to solidify goo into a solid polymer. Very cool, a little more work involved in post processing, the fumes aren't good for you (needs a well ventilated workshop really) and neither is the goo! But the results are smoother, need less post-processing (filing, etc) and usually stronger. Elgoo Mars is a good choice here. It's basically like printing with epoxy resin.. I kinda want one.

    Confused yet, Graham?

    Oh yes, forget powdered sintered metal printing or any of those things - the printers will run into many thousands!

    Skinny, you got your end with a pro for how much? I'm sure Kings Cross is cheaper.

    Aaron, thanks for the reply, I have absolutely no idea what any of it meant!

    I love the forum, simple questions waiting for simple answers and I don't have a clue by the time someone has explained it. Kind of reminds me of school.

    Thanks both of you, I think Father Christmas might want to deliver that package to someone else, beyond my understanding but I'm glad there are those out there that do.

    So.

    How do we get this damn badge to a point where;

    1. we all like it.
    2. someone can make it.
    3. it looks sh*t hot on a cobra?

    Graham.

    Hi,

    During many weeks of enforced idleness when I could not venture into the garage for medical reasons (- a bad episode of eczema which wiser councils had determined to be caused by exposure to toxic chemicals - mainly petrol & oil!!) I spent some time finishing my hybrid gear knob (see below).

    The knob is from the BMW donor vehicle, for the GS6-53DZ gearbox that now sits behind the 1UZ-FE, and the gearshift pattern was replaced with the Lexus / Cobra logo discussed previously on this thread.

    It served to keep me occupied for a time but I now feel the need to return to the real challenge of tuning the 1UZ and getting the car back on the road.

    Take care,
    Ian
