Adjustable Display Stand

thingiverse

This is just a little Display Stand for things like Meteorites. The bottom plate is 7 x 4 cm in size, The adjustable plates are 4 x 5 cm, 4 x 3.5 cm and 4 x 2.5 cm - depending on which size and angle you want to display things. Added a small stand for tiny things with a size of 4 x 2.5 cm. Update 12. July 2023: Added a XL version with a Bottom Plate of 10 x 6 cm and a Back Plate with 8 x 6 cm Assembling: Turn back plate a little sideways into the slit and turn it to 90 degrees. It fits very well and can be put back or forward just to your needs. No glue needed. The slice of the single meteorite shown has a so called Widstätten structure. The Widmanstätten structure is a unique microscopic structure found in iron-nickel meteorites. It is named after Alois von Widmanstätten, an Austrian mineralogist who discovered it in 1808. The Widmanstätten structure forms due to the slow cooling and crystallization of iron-nickel alloys in space. These alloys form a matrix inside the meteorite. During cooling, specific crystal structures known as kamacite and taenite develop. Kamacite crystals have a hexagonal structure, while taenite crystals have a cubic structure. What makes the Widmanstätten structure special is that it can only form under very slow cooling conditions. The exact time required for the formation of this structure depends on various factors such as the size of the meteorite, the initial temperature, and the environment in which it was located. It is believed that the formation of the Widmanstätten structure generally occurs very slowly and may take millions of years. The discovery and study of the Widmanstätten structure have provided important insights into the origin and evolution of meteorites, as well as the processes in the early solar system. It is also a fascinating example of the beautiful and intricate structures that can arise in nature.
