I’ve definitely had my share of nicks and cuts on my hands, but luckily nothing that ever amounted to more than a modest scar.

Oh that’s a nasty pic. A workmate crushed his fingers the other day and it looked pretty similar Sick

I always say, the place a flashlight is needed most is “where the sun don’t shine”!

I finally got a proper an image hosting account today. Dropbox doesn’t seem to work for everyone, and hosting them on my server is cluttering the logs.
I almost chose imgur, but they required me to put my personal cell phone number into their database. NOPE. We all know those things get hacked all the time.
So I chose ImgBB.com. It seems nice. It doesn’t have any basic editor features though, like correcting a sideways image.
I went back and updated my posts with ImgBB links, but there are quoted links I can’t edit. Can I get some help guys? Here are the posts and links you need to know to make it a quick job. It would be much appreciated.

It will be a few weeks until it is due to arrive. I took the cheapest steel option they had, they call it “polished bronzed-silver steel”. That’s going to be an interesting material to check out. It’s been years since I ordered anything from Shapeways, and I have never ordered anything but plastics from them before. This is going to be a first for all of us to explore.

If it’s going to be a few weeks there won’t be time Crying .
There are only effectively 12 days left when you take out the holidays and non delivery days, and then you’ve got to make it and write the whole thing up.
I would quickly try to grab a substitute from somewhere or there is a good chance you won’t be able to finish, and that would be a shame.

Uh, I’ve spent 3 hours trying to make the printer start correctly. It worked perfect all last week. Now it prints 2mm up in the air, and won’t respond to manual adjustment. But otherwise works fine.

As I mentioned in the other thread, this is done, I’ll be posting everything tonight. My family life is very demanding tonight, the posts might come slow.
I did throw together a YouTube video, the link will be posted as soon as the upload is complete.

A quick application of solder paste using the tip of an exacto knife…

Held over a heat gun to reflow…

And bingo.

Then a few wires.

The metal was 4% too small, so I spent about an hour with a Dremel removing material from the inside.
(This is not a one-day build, I fell behind with BLF updates Smile )

Upload complete! Check out the quick video to see what metal 3D prints are really like!

After Dremeling about 0.5mm off the diameter of the MCPCB it installed nice.
As you can see the negative wire is both designed to make contact with the metal 3D print for Ground, as well as make the press-fit easier and more secure.

Then I designed and printed a plastic isolator with a bump to press the positive wire against the battery.
Spoiler alert: It performs more reliably than the button on some Chinese flashlights. Flat Stare

Then I printed the rest in plastic just tonight, that was 4 hours of work to get the printer going for some reason.

Very nice and special flashlight! 3D printing metals has so much potential for flashlights, it is great that you have that going Smile

I agree entirely with you, I even argued for a 3d printed category last year and a no holds barred this year – but sadly it wasn’t included in this competition.
This was discussed beforehand, and the rules stayed the same afterwards. No outsourcing is allowed.
I was under the impression Josh was waiting for sheet to turn up, not a shapeways part (I thought that had been abandoned due to price).

Great that you managed to finish your build, Joshk. Thumbs Up

This is a special format for a flashlight. It looks very nice. I like the 3D printed metal finish. Crown

The floody beam with a slight hotspot is nice, too.

…rules…

The rules were the inspiration. The main argument was that it had never been done before, and people were scared it would be impossible to judge if any work was really done. Well, now BLF has a build thread where they can test their fears. Is it really impossible to judge this? I think it’s clear what I did. Just as clear as any other OL build thread.

So cheers to overly conservative rules, this one is for you.

Cheated.

Disregarded a rule because you did not like a rule.

That is not how “the game” should be played.

There were others who faced a rule that they did not like, a rule that made them make adjustments to their project or forced them to change to a different class. To allow a project that involves a blatant violation of a rule to remain in the competition is a slap in the face to others and an invitation for others to exercise anarchy if there ever is another challenge.

The light that was completed is quite nice. No doubt about that. But that does not override the rule breaking.
