Schlumbergera bridgesii with yellow-ish leaves but surving okay and blooming every year

So this is a "supermarket Christmas cactus" I bought in 2020 or 2021. I think as far as I can remember it turned into this yellow-ish color soon after I bought it. I thought I killed it but it turns out blooming every year since then. I did move it to a larger pot and layer added orchid medium instead of potting mix. I also added orchid food. The pot does have drain holes. I have tried keeping it either outdoors or indoors (but avoid outdoors during the hottest and coldest months) and nothing seems to help.

I live in South Carolina, USA. USDA zone 8a.

When indoors I put the plant in my sun room, which has large south-east and south-west windows. When outdoors the south-west side is shaded.

Water every two to three days when indoors (I keep my indoor humidity at around 55%) and everyday when outdoors. When watering I water till excessive water comes out from the drain holes. Since it is on orchid medium I assume it is fine since excessive water won't stay, is it correct?

▲ 85 r/telescopes

I bid on a telescope with limited information. It arrived today.

The only info I got when bidding on it were several blurry photos, in which I can tell that the diagonal says astro-physics maxbright(!!). Also there is the orange Celestron label on the telescope.

I mean that diagonal is a $400 item right? I didn't know what condition it was in, but what can go wrong?

I won the bid and my final cost including tax and ship is about $75.

It arrived today. First of all, yes it has an astro-physics max right 2" diagonal. The mirror itself seems a bit dusty but overall damage free. Jackpot!

The telescope itself is bigger than what I expected. The objective lens measures 100mm. It is a bit dirty and with some smears. The tube plus the focuser is not much longer than my vixen 90/1000, so this one is a 100/1000 or 100/1100 I assume? There is really no other mark that I can find other than the orange Celestron. Can it be a vixen? Or is it a younger, made in Taiwan "Halloween" telescope?

The telescope is held with a couple of rings with three screws on each. I think they are meant for the L type dovetail bar? The current dovetail bar is 3d printed and will fit a vixen type clamp.

The whole set (no eyepieces no fonder) weighs about 7.8lbs. the diagonal itself is a 1.1lb beast.

I haven't got a chance to test it yet. South Carolina upstate just got some long needed rain this morning so I won't complain too much. Also I need to figure out how to securely mount it first.

I have several questions regarding this set. I will post them in a reply.

▲ 3 r/resinprinting

Ok I know I know the best way is to not edit the mesh file but the original car/obj file. But often the mesh is all what we get and I need/want to chut them for faster printing and/or better support options.

I know most slicer software has a built in cutter. But as far as I know they just cut the model into two on a single plan. Sometimes, for example, I may want to print the head of a figure separately, and I want the seam to be at the neck, which I can hide easily, but the simple cutter will just also unavoidably cut the hair and even the chin.

I have watched some guide that in the Meshmixer you can select the specific region you want to cut, then make the cut, then separate the shells. I've tried it. It worked but the process was rather complex and more importantly meshmoxer just doesn't run well on my computer (it is CPU heavy and doesn't use gpu?).

I also wish I can add the matching peg/hole easily on the cut. Or even making non-flat cuts to ensure fool-proof assembling, if possible. Is there any software (running on windows PC preferably) that can do this in a more simple and intuitive way?

"This function should not be that hard to make, right?" Said I, who knows nothing about programming and 3d modeling 😅

▲ 2 r/telescopes

Sorry no picture in hand. I hope my description is clear enough but if people want I can go dig into my "random telescope sh_t" crate.

So a while back I got a bunch of random telescope hardware for cheap. Among them are several rings that seem to be capable of holding something with 90mm+ OD. Unlike the common tube rings they are not split in half but solid rings, each with three screws (with sprigged tips maybe) arranged in a 120 degree pattern. Yes they just seem like enlarged version of regular finderscope rings.

I am wondering what are they for? Are they simply for mounting larger finderscopes on to huge main telescopes? Or are there certain circumstances that it make sense to mount a, say, 70-90mm refractor, as the main telescope, to that kind of rings?
