Hi, I have shared the design and you can now download the Piñasphere STLs for free from Thingiverse: https://www.thingiverse.com/jean_r_built/designs

Here a bonus pic of the weight check, for a higher resolution pic check my Flickr Piñasphere Album: And obviously a pic of myself and my creation we shot it for fun.

Open Air: I like it both ways, I admit that this spring I underestimated the charm of the Open Air configuration, it has grown on me. How it looks at home:

Enclosed:

All the printing was done with the 3D printer inside the soft enclosure. Between every prints I did a deep cleaning of the printer, and print bed leveled. The direct extruder configuration also helps with the deep cleaning, I had to fine tune it again especially the retraction settings, but now it works like a charm and i can also do a deep purge with a thick long needle, it helps a lot to get clean prints. As you can see in the photos, when printing with clear PETG, the temp were 250°C for the hot end and 90°C for the Bed. This way the parts come out transparent, I could have made them more clear, but I needed them to be strong, so thicker, this made them have a frosty look which thankfully I like. The rPET was tricky, because I could not use the same settings as the other PETG filaments, I had to print it 10°C cooler and slower, or it would print a brittle part. Generally speaking not considering the clear parts, I avoided Ironing in this project, especially for the white parts, as the risk for burnt stains was to high.

The Workhorse of the whole build has been my Creality Ender 3 Pro, which I modified to be quieter during night operation as some parts took more that 24 hours to print. Printing the clear PETG parts with a hot bed wasn't kind with the original bed, so when it gave up I went with a PEI one, so far I like it you just have to be careful with the preheat phase, and have more patience at the end with the cooling phase. The main reason for the hot bed with the clear PETG parts, is that the hotter the more clear they will come in the end. for the finishing process, this time around was mostly precision cutter work as I didn't want to paint the parts for this project. To avoid extra finishing work, I took more care when deciding the printing orientation of the parts and fine tuned the supports.

Even though it doesn't look that important structurally, the SSD frame needed 3 iteration before being what it is now. it has to allow for 2 2.5" SSD and keep the antennas in place, while minimizing the slowing of the airflow. I had to try different iterations, also because the first one was to uncomfortable to assembly, so it was a bit of trial and errors. Another part that was hard to implement in the design, were the I/O access faces, on the front side I was able to keep the first receding design, while for the back I needed more clearance for the power connector so I went with a full slice of the dome.

The Radiator side has a different situation here the exploded model animation As you can see the internal dome is floating: This is because on this side the radiator is protected by the dome, but is also a structural part to keep everything in place. In the next photo you can see how it is fastened to the Radiator Frame Well speaking about this pic, even if not very glamorous, you can also see the routing passages for the tubing and the fan cable. There are also the parts to which the external domes attach to, but it wasn't the main purpose of the pic so they just happen to be there.

Here three pics of the bonding process of the internal Mobo Dome Then had to leave it for 24H to settle, now it's just like it is one part.

Here some more pictures of the Mobo side without the dome. In the next 2 photos, you can see some of the "missing" parts of the explosion animation, everything is functional in this project because there isn't much space left inside. In the last pic some cables that are usually hidden by the dome, here you can see the 6 wire cable of the power button, SSD and power led, all end inside the black domes support that has enough space inside for those cables.

Then let's see the Mobo side, it's less complex, not because it has less parts, but only because most have been glued together with clear epoxy so now four parts are one complex dome. As you can see, there is a big dome that pop out giving access to the motherboard. Talking about the motherboard here it is how it looks with the dome popped out of the way: Without the Waterblock it looks like this: I almost forgot, the motherboard is an Asrock X300M-STX, it is a sub ITX Motherboard it is about 140x147 mm while a normal Mini ITX is 170x170 mm. The Asrock motherboard came from an Asrock Deskmini X300 Barebone PC. You can clearly see that the CPU is a Ryzen7 5700G, at first it had 2x8Gb of Ram but the final build has 2x32Gb of Ram at 3200 Mhz. It is visible the main 1Tb Samsung SSD980, there is another 1TB Samsung SSD980 M.2 under the Motherboard, but obviously it is not visible here.

Now I'll show you some simplified exploding models of Piñasphere. I want to specify why I consider the model simplified, it's because there are a lot of missing parts in the videos, but there are enough to understand the main structure. I'll start with the central ring: There are missing parts but you can see the sandwiched superstructure, composed mainly by the Mobo and SSD frames squeezing the central ring layers. You cant see the bodies that serve also as anchoring points for the white external domes, they have also space inside to help cables routing, one contain the main structure for the power button.
