For my projects involving chemicals, I needed some test tubes and something to store them in.
I made 2 versions, 1 with plastic tubes that are actually plastic bottle prefabs(A plastic bottle before it is blown into the right shape). And 1 version with glass test tubes, the glass tubes were used to put the sugar beans<\/a> in at my birth and so I find it quite fitting I now actually use them for science.<\/p>\n\n\n\n

Glass tubes<\/h2>\n\n\n\n

The first step is to make a quick sketch with roughly the correct dimensions and shape
To make the legs fit nicely into the bottom and top parts the insertion on the legs is 0.5mm smaller than the holes it has to fit into. this makes it easy to assemble and with some glue, it won’t come apart easily.<\/p>\n\n\n\n

Then extrude it and make it 3D<\/p>\n\n\n\n

Then add some text, number the holes and fillet all the cornors and it alreadly looks quite good<\/p>\n\n\n\n

Now in reality it took a bit of trial and error to design this since I only just started to use fusion 360 for 3D modeling.
After I created the model is was really easy to 3D print it with PLA plastic and some basic settings.<\/p>\n\n\n\n
