Functional Nylon 3D Print Needed -

I need a durable nylon part printed for real-world use. These are bun feet 43mm designed to raise the height of 4 chairs. They need to withstand maximum loads of say 100kg. They should be a matt black coloured material... (Budget: $250 - $750 AUD, Jobs: 3D Modelling, 3D Printing, CAD/CAM, Solidworks)
