No worries. Found a couple of extra pics on this PC. Here is one of the hull sections fresh off the printer. Printed in the cheapest clear PLA I could find on ebay, I think it was something like £12 for 1KG. And here is a shot of all sections stuck together and flooding the inside with resin.

Could you make centre caps for alloy wheels with one of these? As the ones for my alloys are no longer available and i am missing two. Might be another avenue for you to look at. Alloys in question are 10" mini exacton / 1100 special edition. Long answer is yes with an "if", short answer is no with a "but". I've done quite a few, it's no issue for a well tuned printer, these were the first test ones I printed - I've upgraded the printer a lot since, I can get them far better now, but even these were pretty good:

Those are PET-G, but HT PLA works if you anneal it too.

What about your printer? DIY or did you plum for a decent expensive one?
I'm about to swap out my motors for 0.9* ones, fit either a 2-1 or 3-1 extruder with 1 direct drive and 1/2 boden drives (did think about giving a Kraken a go, that's got 4 nozzles, all 2-1 feeds so 8 filaments all bodens but thought "what would be the point???" lol) and swap my main board for either a ramps1.4 or something similar.

Replicator clone base but heavily modified, ally carriage, split pre-loaded bearings, linear rails on ally extrusion for Y, dual extrusion, copper blocks, nozzles, etc. I'm just about to build another one as it's getting a bit small for what I need, probably with a Tiny-G board for the better motion controllers.

Being a computer luddite I have no idea what half of the things mentioned in this thread are, but I love the things you guys are creating, and the fact that you're still tinkering (I don't mean that rudely) with your creations to improve them. That and the fact that you're all just chipping in with different bits & bobs on how you've worked round supposed limitations (like the sanding issue). Sharing info to help each other out strikes me as one of the best things about this whole RR forum, regardless of the topic. lewist123 - wasn't Calypso Jaques Cousteau's boat? Fine looking model. Edited to ad - I'm amused that I now have an ad for Markforged "stong 3D printed components" in my browser; especially the fact it says they're 23 times stronger than other 3D printers - not 20, not 25, oh no - 23 times!

They're going to struggle with that 23 times vs some of the 3d printed titanium parts...

Has any one any recommendations on a good reasonably affordable cad package to use?
My son has a 3D printer and has printed a variety of models he has downloaded, we have also managed a couple of simple items from sketch up, I last used 3 modelling software 30 years ago and even that seemed easier than sketch up!

Scalextric chassis for my 3 cosworth shells . I was thinking about how and what you would use to design a chassis from scratch.

So I am currently building the MK3, and am considering building a delta tower too.
Parts have arrived for the new one. Full spec:
Adruino Due main board Arduino RADDS V1.5 32 bit controller RAPS 128 stepper drivers x 6 Nema 17 0.9* steppers 2 x Bondtech BMG boden extruders E3D Legends dual hot end (so has both the cyclops and the Chimera ends so I can switch depending what I'm doing)
Stainless frame again...
So, capable of 128 micro steps per revolution, printing two filaments at the same time, and much much higher resolution prints at a much higher pace. Should think so too for the price tag of the parts... The hot end alone cost significantly more than the whole of my first printer!!

Haha, wait until you have fun levelling both nozzles. I curse mine 95% of the time, then love it the 5% when I'm using two materials..

But I don't want a water cooled system... Besides can't think of a use case for a 4 nozzle system. In either case, have the choice of 2-1 or dual now. Best of both worlds!

I'm planning my next built at the minute but I think I'm going to go with the 2 flying extruders design - so the two hotends are independent, the nozzle levelling is not so critical then as you don't get the unused nozzle dragging over the print. Makes the belt runs a nightmare instead I'm amazed nobody has managed to produce an aftermarket version of the CEL dual nozzle yet though, that rocks them across a pivot so one comes close and one moves away - even has a needle that seals the unused nozzle.

Oh I like that idea!! A lot!! I might just have to make some cad drawings... My next will be a delta I think. Though I REALLY want to build a robotic arm system with a turntable on the bed.

Can you explain / show photos of the whole extruder set up? I understand the Cnc part of moving the nozzle around,but what controls the temp and feeds the filament? Does the nozzle have a valve in it to shut off when you move to a new position? I.e. If you are printing something with holes in it.The 3d model bit is easy,but what breaks that down into the layers that you print?
