- Comment on World's Biggest Battery Will Provide 85 Megawatts to New England Grid 2 months ago:
8.5 GWh / 85 MW = 100 hours, or around 4 days. If they can build it cheap enough, this is the kind of battery we would need to replace nuclear for dealing with the day-to-day variability of renewables.
- Comment on Nvidia is ditching dedicated G-Sync modules to push back against FreeSync’s ubiquity 2 months ago:
Will the Mediatek modules also support VESA Adaptive Sync, or will they have fixed frame rate on AMD cards?

github.com/aconz2/Fusion360Exporter lets you bulk export all of your projects to local storage.
- Comment on Prusa slicer 2.8 UI changes 3 months ago:
There is some good stuff in this release. Go to Preferences > GUI and check “Show sidebar collapse/expand button” + “Settings in non-modal window”. Now you can put the Preview and Print Settings windows side-by-side, and see the result of every change immediately. This also requires “Background processing”, but that’s been available for ages.
- Comment on OrcaSlicer V2.1.0 Official Release 4 months ago:
all the features you know and love from things up the tree
Did OrcaSlicer ever bring back the option to slice automatically when changing settings? It’s called “Background processing” in PrusaSlicer.

Seems risky, because people don’t expect chocolate to need refrigeration.

- Comment on Sandpaper Adapter for Oscillating Multitool 8 months ago:
PLA, but I’ve only used it for sanding small models so heat wasn’t an issue. PETG should be more heat resistant.
- Comment on Sandpaper Adapter for Oscillating Multitool 8 months ago:
Yeah, but those sanding pads cost more than generic sandpaper.

- Comment on Sandpaper Adapter for Oscillating Multitool 8 months ago:
Does mechanical error actually matter when using sandpaper? It seems like most of the error comes from holding the tool with your hands.

nice 45° angles.
- Comment on FreeCAD Make-A-Box Generator 8 months ago:
I suggest uploading some default-size STLs so we can view the parts in 3D.
- Comment on Sometimes fewer walls are better 8 months ago:
I haven’t done any tests where the tensile/breaking strength is relevant, just rigidity. Maybe it’s possible to optimize the infill based on finite element analysis or something, but that’s not a rabbit hole I’m looking to go down.
- Comment on Sometimes fewer walls are better 8 months ago:
Okay, but if my 2-wall hook bends into a straight line, then I don’t really care about the durability of that no-longer-hook-shaped object.
- Comment on Sometimes fewer walls are better 8 months ago:
It’s not really clear what you’re saying, because they’re both “my design”. Could you specify 1 wall vs. 2 wall?
- Comment on Sometimes fewer walls are better 8 months ago:
I just tested this hook by hanging a 5 gallon bucket and gradually adding water. 1 wall = 1710 g, 2 wall = 1178 g. The thing is, a 1.5 mm PLA hook fails by unrolling rather than snapping, so rigidity is more important than strength.
- Comment on Sometimes fewer walls are better 8 months ago:
Lock some calipers (with a rod sticking out) to 1.5mm shorter than the part height, compress it down onto a kitchen scale until the rod is just touching the platform, and record the weight.
That’s just the first procedure that came to mind. I will try to think of a way to do a hook strength test today.

What exactly are your modifiers modifying?

So you’re saying it’s technically a pirate ship?
- Comment on Floating Benchy 8 months ago:
You can see in the photo that the wall is just above the waterline. It stays in that orientation until you disturb it enough to spill water over the edge, at which point it capsizes.
- Comment on Floating Benchy 8 months ago:
It’s not rocket surgery. Boats need more weight at the bottom than the top. If you put it in water and it leans, shift some weight in the other direction.
PrusaSlicer has a ‘center of gravity’ indicator that removes at least some of the guesswork.
- Comment on Floating Benchy 8 months ago:
The technique can be applied to other models: Use PrusaSlicer’s ‘cut’ feature to break the model into parts, and tweak the settings (mainly infill and perimeters) to give each part the desired density.
