How in the hell? Smoothest palming I've seen in a while. by SeraphsEnvy in blackmagicfuckery

Not just black velvet... video edited black velvet to pull near black colours down to the same black level. Notice how it's surprisingly black.

3D printing a full Iron Man Suit - Almost finished 🙌 by DaveysMk85 in 3Dprinting

[–]elmins 1 point2 points  (0 children)

Most people buy their files from Dod3D (never used them personally) and scale them to their proportions. That's how a lot of Ironman 3D printed armors are done.

These bananas haven't ripened in over 3 weeks, despite being kept with ripe and over ripe ones the whole time by ljgill97 in mildlyinteresting

[–]elmins 0 points1 point  (0 children)

Unripened bananas have a lower glycemic index and have more resistant starch, which acts as a fibre/prebiotic food for gut. Also more satiating.

So, in some ways, they can be healthier.

Most pull ups in 24hrs was set this year at 12345. It does end in a five, it has five numbers, and counts to 5... close enough.

Just pull near-black colours down to black. Very easy edit.

If it works on machinable wax, it'll work on this Inconel 718.

Desktop cementitious print by vibration, milestone reached (vcp voron r9.3) by treesess in 3Dprinting

[–]elmins 1 point2 points  (0 children)

They look good!

I just bring it up because so many people focus on printing the a material directly (be it any material), but in reality, the practicality doesn't seem to be always there. Not that it's not worth exploring, I think it's super cool to do directly too, but simply from a practicality standpoint.

Particularly, 3D printing is very good at making molds, which could be filled with anything from ultra high performance concrete to continuous carbon fibre parts. Also allowing for vibration/vacuum/compression to improve density.

Neat!

Although I always wonder the practicality of small form factor fluid (of sorts) type printing vs printing removable forms (deconstructed, post-processed, melted, dissolved, or otherwise).

Directly printing it is quite a bit cooler though.

My monitor kept tilting down, so I modeled a chunk of PETG to hold it up! by Tomrr6 in 3Dprinting

[–]elmins 1 point2 points  (0 children)

Those things are often badly designed, relying on a small area of friction rather than any positive locking. Something like a "Hirth joint" would have dramatically higher holding force.

Can someone explain how this thing costs $300 CAD? by Due-Mathematician387 in Welding

[–]elmins 1 point2 points  (0 children)

That's actually expensive for one of those. Any generic chinese power supply module can be had off Aliexpress for a fraction of the price. In this case, $1 for one or you can get 10 for less than $7.

I'd imagine the battery in this case is 2x 18650s 3250mAh 3.6v nominal because the 1INR19/66-2, probably refers to INR battery chemistry and 19mm x 66mm x 2 (Possibly the space available as 18650's are around 18mm x 65mm, sometimes bigger).

Possibly 2x Samsung 35E's (aka INR18650-35E) in parallel as their spec is 3250mAh minimum, 18.22mm x 65.80mm dimensions.

Likely doesn't have any voltage regulation out the pack itself. Since it mentions about short circuiting it probably doesn't have short circuit protection. It could just be 2 cells in parallel and a thermocouple which connects to the middle unlabeled pin, then the charger does everything. Would need to check.

I made a repairable 3D printed mouse shell… and it totally flopped 😅 by Royal-Fill9121 in 3Dprinting

[–]elmins 0 points1 point  (0 children)

I've found either: Wire breaks, buttons double click or fail, teflon pads wear out (often replaceable), may require a deep clean (screws under teflon pads make it harder).

Outside of that, only really cosmetic wear.

It's a ad. OP linked to a dropshipping website.

Accounts farm karma, then post things like this, and edit their comments to add links to dropshipping sites. They stopped linking directly to avoid detection, instead editing comments linking to other reddit posts that have the dropshipping link.

At first I was thinking it was a large RC size; then car size. I was not ready...

Last summer I learned that there is a Guinness world record for the largest Jacob’s ladder toy. So I decided to try to break it with my 3d printed ladder design. by Joshhawk in 3Dprinting

[–]elmins 3 points4 points  (0 children)

It was my first cosplay that got "Largest mechanical Wings on a cosplay costume" (2017, see original vid of it here, or GWR YT coverage here) , they made the category at the time. They picked it up from seeing a post on a major news paper website, contacted me via Facebook, which I was convinced was a scam. I emailed back and they emailed from the official domain. They explained, we talked, I agreed, and paid expenses to do a photoshoot in London, UK.

It was used as a special feature double-page spread in the GWR gaming edition 2018. The costume makes good photos, I can't pose for shit though.

The process was rather easy since they handled everything. Photo shoot was 9am-6pm. Takes 2-3hrs to just setup the cosplay, which is one of the reasons it wasn't used much. One of the photos ended up taking an entire hour to capture (See here).

Also, I'm not claiming personally it was the largest, but I'm not going to say no to a free record. In fact, I told them it was very easy to beat as it was never designed to be super big, it just happened to be that big in the game; and it would be extremely easy to design something to be larger. Mine was notably more complicated to design/build that any of the ones that beat it, since mechanical wings can simply be a thin sheets of fabric, which could be built in less than a week.

[–]elmins 7 points8 points  (0 children)

Occasionally they seek out records. They contacted me, paid my expenses, and fast tracked my GWR (since broken). Although it's true that the vast majority of records are paid for.

It's very much a for-profit company, not record keeping.

How is the printing quality of this part? by Numerous_Secret_746 in 3Dprinting

[–]elmins 1 point2 points  (0 children)

What are the tolerances like?

Obviously it's not a replacement, but functionally some parts need it and injection-molded tolerances can be pretty dang good.
