3D printing does get addictive.  You rapidly end up when faced with a problem thinking "can I design and print something to do that ?" 

I bought a Creality CR6SE a couple of years ago with no real idea why I wanted one other than curiousity. A mate told me to try Fusion 360 for design and after a fairly steep learning curve you get into the swing with it.

I started off making some badges which is fairly easy using PLA+. After a while I had a go at creating a simple tool for marking arrows (archery) which is basically a copy of a commercial item which I'd tried to buy but was NLA.   That turned out very well, is probably on Version 9999 now but makes fletching vanes very simple and 100% accurate.

The problem for car related items isn't making them but temperature in use, for example the dash top vents will see a lot of heat during summer (well, maybe not in the UK) and softening can be a problem with PLA. It'll work fine for a prototype but long term you'll want a more temparture resistant material.

I was also toying with the idea of making new shafts and hubs to ~original spec, with obvious modifications like shortening the splines and using 30mm bore bearings on both ends, but also using better material and hardening the splines. Maybe a different spline profile if deemed necessary, but otherwise drop-in for the Europa. They really should be replaced as a pair anyway.
It may turn out that a fundamentally different layout of the components is necessary (moving the splines to the yoke side, as seen in some unobtanium designs), but I wouldn't go so far as changing the u-joint size or otherwise messing with the fundamental Europa suspension design. 

We have a fairly similar part at work that should serve as decent price comparison (no u-joint yokes though), going to find out what those cost for the small initial batch. If the cost is ~$800 per car at qty 6-10 I'll likely put in the effort to do that. 

If anybody is reading this in a few months, please bug me to update. I'll get to a y/n decision on feasibility and make a fresh post.

I was "This close" to getting a nice VMC recently but just could not quite get it done.
I was gifted a decent beginner grade 3D printer in its place.
Fairly frustrating machine but I am getting the hang of it.
Turns out that PVA is tougher stuff than I expected.
If not for the layer lines it would make nice vent grills, it may yet make sand-casting patterns.
There are supposed to be some other filaments that can be smoothed after print.
The main benefit of this machine for now is that I finally have a motivation to brush up my G-Code and a way to confirm what I've drawn.

First real part I have made is a bracket to hold a dial indicator in place rather than setting the Z (Vertical hight) with a piece of paper and "Feel".
Running second one now just to have a spare, they are plastic.

I never did get a reply
Maybe we need to organize a group buy.
Selling several sets all at once might get him something expensive he is looking for?

You likely won't be able to get a report, and I'm not sure how much help it would be anyway.

I have an S1 with a S2 front end grafted on...that's definitely not on any kind of report. Nor the countless other bodge fixes in 40-odd years of ownership.

Any luck getting in contact Richard?
Just ripped out my S1's trailing arms and have discovered some impressively worn splines, had the reinforced Triumph puller out and everything but the hub just fell right off the axle. I'll probably need both the axles and hubs.

Looks like Banks has the hubs and shafts for £1k GBP (1 car set)...if he would reply to emails at some point.
I recall seeing some solution kit on eBay as well, but all dead links now.

I'd rather not deal with going too far from the book on these; pretty sure modifying the original parts is completely out of the question. Not enough material left in the hub.

Hi

It seems that in the US you can register a car as anything you like. Mine was a Lotu Champion with the Vin number 3940R.

Yes, you can remove the cover in situ.

READ THE MANUAL CAREFULLY

If disassembled improperly, you will drop a detent ball inside the main casings, not good!

I have tried numerous sites, and they all require 17 digits.  Even with a license plate nothing comes up.
