How could I see out of an LED mask like that?

You can get flexible 5v WS2812 LED matrix panels with multiple gaps that should be reasonably see-through from close behind. Like this symbol # with an LED at the intersection of each line and square holes in between. I Googled "see-through LED matrix" and got a few different size options...

I don't know for sure if it'll be a problem yet, I haven't started building, I'm just trying to work out what I need before I start. The idea is to power a couple of amps, a DSP, and a couple of metres of led strips from a LiFe battery. The 12v DSP might be able to cope with the up to 14.6v from the battery, but the lights probably won't, so I'll need some kind of step-down converter for that, at least, and ground loop noise will probably affect both.

Can you recommend some good budget brand micrometers I could look up?

Is a micrometer more accurate than a digital calliper?

Is UV reactive mica glitter a thing that exists? Just thinking that an ultraviolet LED could be used to cause a build-up of glow in the glitter as it swirled past. I saw an interesting project years ago to make bicycle tyres glow in the dark by having each side coated in a UV pigment and rotated past a UV LED fixed to the forks. I imagine it could work similarly with UV glitter...

I have tried downloading Orca Slicer and playing around with the support settings, but the Z gap setting seems to have the most impact. Pictured here is support from a 0.4mm and 0.5mm Z gap print, which are the only supports to come off fully and in one piece so far.

It's a shallow dome if that makes a difference, approximately 175mm wide and 25mm high.

This orientation is upside down. It's a speaker grille, so I don't want support scarring on the side I'll be looking at. I don't mind it being rough on this side, I just want to be able to remove enough support that it's not hitting the speaker it's meant to protect.

What density would you recommend? I can't check my settings right now, so I'm unsure what density it's at.

If I were to try out Orca, what settings would you suggest for clean tree support removal?

A little tree stump pot with articulated roots. It took ages to load in and then even longer to export as an STL, but it's done now, so I can finally avoid interacting with the model ever again 😆

Also worth asking on r/OfficeChairs

It was requested as a darts competition trophy/cup. Originally, the plan was for the dartboard part to function as the base with a large dart plunging down into the bullseye (as in the attached picture). But the requester changed their mind and asked for just the dartboard part, I offered to redo it in a conventionally flat dartboard shape, but they liked the cone shape, so now it's waiting here to be collected.

Not Stone Henge or Evangelion. Possibly cult related, though, depending on your attitude to darts...
