3D Printer Filament Scale
It is handy to be able to check the weight of filament on a spool to make sure that the filament does not run out while printing something that will take many hours to print. I found this very clever design on cults3d https://cults3d.com/en/3d-model/tool/filament-holder-and-scales which I decided to build, here are some pictures of the…
Bacteria Samples
Hypothesis The intention for this experiment was to take bacteria samples on different objects commonly found inside a household and see which surfaces has the most bacteria. these surfaces were tested: toilet seat mobile phone kitchen counter human feet inside of human mouth This experiment will also prove that agar we selected could grow bacteria…
Some Different Shaped Rockets v4
What we learned from the last experiment was that the rocket wasn’t dropping is fuel fast enough and was trying to take off carrying the full weight. We needed to find a way to expel the fuel faster, so may be a cork in the bottle instead of a nozzle. Sticking with the 25g baking…
Vertical Rocket Sled v3
So moving on from the sled, we tried to launch it vertically …that was interesting… Clearly the rocket is too heavy to take off, but once it looses weight it takes off. So, a couple of things to try on the next iteration: Bigger nozzle – maybe a cork instead of nozzle Smaller rocket Get…
Rocket Science
Having seen what Chris and Kian had achieved with their rocket I attempted to build a traditional rocket made from a tube. As seen in the photo most parts are 3D printed, from the left we have 1. a threaded nose cone with a fibre washer to seal the top of a tube 2. Next…
Rocket Sled v2
For the last few weekends we’ve been experimenting with a vinegar and baking soda rocket. This is the second iteration After the last iteration, as the sled accelerated away, it hit the back tyre of the ute and bent both axles. This iteration we strengthened the axles and more accurately measured ratio of vinegar and…
