Floating Virus

Description

Don't be afraid! This particular virus is harmless, you don't need to keep your distance! ;-) Some time ago I found this “beautiful” corona virus model by gregbejtlich here on Thingiverse. My idea was to include this model in my tensegrity collection. Of course I had to change or add some things. It is also slightly scaled up. The thread in the middle of the two half rings - besides the three threads connecting the virus and the base - builds the tension in this object. It's a bit magical how the physical conditions create a tension that makes this object a unit - a perfect unit. At first sight a bit confusing ... you have to look twice to understand the principle. To get printing color ideas for the tensegrity model, have a look here: https://youtu.be/baDhDU0rU0c Dimensions: Virus Ø approx. 94mm, H approx. 180mm, socket Ø 80mm Printing of the virus: I recommend the printing of the virus in 2 parts, because this way less supports are used in the slicer and therefore the printing time is reduced considerably. There is a mark on each half of the virus for the correct gluing of the two halves. These must lie on top of each other when assembling. However, before the two halves are glued together, it should be noted that they also determine the alignment of the upper ring half. See photos! I glued the upper half of the virus only at the very end, after the threads have been attached. The creation of the "tensegrity "and the final fixing of the threads is exclusively done in the base! At the other end of the threads only a multiple knot is required. The assembly should ideally be done with a nylon thread Ø 0.35mm, as the widths of the fixing slits in the base are designed for this. It is best to start by making the connection between the two half rings. The distance between the rings should be about 25mm. This is not very easy and needs some patience to set the second knot so that this distance is created. Several attempts may be necessary. Now insert the half rings. To ensure a good fit, the fitting accuracy is very tight. It may be necessary to correct the fit with a cutter knife or sandpaper! There is an arrow on the bottom of the base. This arrow indicates the direction in which the lower half ring must be inserted into the base! There is also an arrow on the underside of the virus. This arrow indicates the direction in which the upper half ring must be inserted into the virus! This can also be seen in the pictures. Then cut 3 threads of about 25-30 cm. Start with the 3 threads and guide them through the suction cups with the holes. It will be a bit fiddly now. It may be that the small holes are blocked by supporting material. Normally it is sufficient to pierce them with a sewing needle. Place the model with the bottom side facing up on the virus half. Then pull the threas through the corresponding holes in the base At first just clamp the strings. Than you can start with the adjustment. So when the strings are slightly tightened, socket and virus half are aligned horizontally, then you can secure the strings. Finally, glue the upper half of the virus to its underside. Hurray! That's it! … the virus is floating! The attached pics will surely help you with the assembly. I hope that I did not forget anything in my description. If you have any questions please contact me!
