This is a rotary cylindrical periodic table with hexagonal patterns (That reminds to a carbon nanotube), where each element show its abbreviation, mass and atomic weight, therefore, it is very useful and didactic, as well as artistic.
Diameter: 199.4 mm
Total height (full assembly): 324 mm
Total weight: 759 g

If you want to print this, to clarify possible doubts, you must first read all the following information:
• For some printers, printing the hexagonal pattern can be a bit difficult without supports. If you print it on PLA with a lot of ventilation, there should be no problems. I use a layer height of 0.3 mm, 100% layer fan and only support for a specific part (see attached images). I include a STL called "Test" to see if your printer will be able to correctly print the body of the periodic table with its patterns, if you have doubts.
• Important: You have to join the Honey Body Bottom and Honey Body Bottom top in the correct position, in the images you can see a suggestion for you to guide.
• To join the two parts of the body, I recommend first sanding the contact surface a little. Then apply a glue. In my case, I used a glue called "La gotita" (that is the name of the glue in my country, but I know that also it is known like cyanoacrylate or super glue) with sodium bicarbonate. This combination generates a very strong union.
• I designed the ball bearing to be printed with a layer height of 0.175 mm, so it is better to respect it.
• I recommend printing it with a speed equal or lower than 50 mm/s.
• It includes a support that ensures that it prints well. It must be easy to remove. The ball bearing work well.
• Each element is joined by pressure.
• Before printing all the elements, it is a good idea to print a test and see that they fit well in the hexagonal pattern. Depending on your printer, a small scale may be necessary to fit securely. For example, in my case, I had to scale them on the x and y axis by 100.3% (0.3% larger in those axes) , and with that, they fit very well by pressure.
• You can find the elements ordered in groups in the uploaded files.
• You can choose the colors you want. In my case, I gave colors respecting the visible electromagnetic spectrum, and because I did not have an extra color to the halogens (it would have been great to print them of dark blue and the noble gases of violet), I included them inside the nonmetals group.
• The filament change technique allows the hexagon to have a color, and the element abbreviation, mass and atomic weight, another color, which generates a contrast that allows distinguishing it better. Since my printer is a “Prusa MK2” I use the page https://www.prusaprinters.org/color-print/ to do the filament change. I do not know if this method works for other printers, but you have other options:
* Using Simplify3D (I don’t know methods for other slicers)
Watch this video and read its description: https://www.youtube.com/watch?v=OiixypnOS8o
It is more tedious, but you can pause the impression and change the filament, at the desired moment.
