I been thinking that we should have a file repository for making it easy for people to find anything that might be of use to them for laser or 3d printing. I will start this of with a small stl file which comes in useful for both these technologies. It should take about 5 minutes each to print and weighs 1Gram which is less than 5c each. The magnets can be found on ebay easily enough such as this one - https://www.ebay.com.au/itm/Super-Strong-N35-Round-Disc-Neodymium-Mini-Fridge-Magnets-Rare-Ear
