OK, after several requests for my back covers, and me stalling because I had not made a parametric version, I realized you could simply scale the print height in your slicer to get the right width (since they print standing up), and it should hopefully work OK. So, here’s a link to them:
Please let me know if you spot any problems or have any issues.
Very sleek! Thanks Doug!
Hopefully will get to this eventually. I may cut (boolean operation) a hole/slot for my middle cover, where the wires for the core emerge.
After I get back home from our road trip (Lord willing, safely — we’re currently coming over a mountain pass, on icy roads with blowing snow, with wrecked cars off to the side), I will aim to produce multiple sets of this with incremental length differences, such as maybe 165 mm, 170 mm, 175 mm, etc. etc. so that someone could just pick the one that’s closest to their actual length and not have to scale it by so much.
Thanks Doug. Colin’s got a good idea. I’d also like to see if I can print the triangles in a different support material.
Awesome work as always.
Steering wheel in one hand, browsing the v1e forums in the other? Safe travels!
I should have made clear that I am not the one piloting the vehicle! I am safely in the passenger seat, while occasionally browsing the V1E forum.
They break away effortlessly. Or at least they do for me. I put them just close enough to help and just far enough away that it should break away without leaving a mark.
Thanks Doug. 
Some feedback:
Using Bambu Studio, very easy to adjust size/scale. Assume other slicers are similar.
Also, Successfully printing version without support (X1 Carbon, PLA).

Thanks!
The ease of scaling is a key to why this works. The idea for providing a variety of starting points is to keep from having to scale by a huge amount, because it will skew the screw holes by more than is perhaps desirable.
This is great. The owners of CoreXY machines will have better chances than those with bed slingers. Bed slingers would definitely want the break-away support fins.
Thanks for another fantastic mod Doug!
I watched a YouTube video recently in which it was pointed out that several nations independently achieved invention of radar about the same time. It was an idea that occurred to various people. Same with this decorative thing. Several people have had the same basic idea, with minor differences in how it is implemented.
Yeah, at least two people started making the LR4 nice before even having finished the Beta build. It was a swell time. 
Yep. I had them on my beta, my RC1, and redid them again on my RC3. I have not yet done them on full size final LR4 which is now complete. I may do them on the full size too, but if so, this time I got the horse before the cart.
I’m going to post the first make on printables… as soon as this finishes.
it is silver silk pla and check out that hair!
Whenever I have stringing like that, I hit it with a heat gun and it melts them right off.
me too. This silver silk seems to be more prone to it than regular pla. But I really like the finish on it.
Thanks Doug! These look great. Gonna do these up tomorrow!
Just cause anytime I see a long topic name this always pops up in my head though so thanks for the chuckle too lol
At least we trained Doug not to do it in all caps. 
It did look good though.
