Summary All of the parts needed to build an educational hydraulic arm kit for a classroom. This has been remixed from Kidraulic files, but changed to reflect my use of them. Major changes include changing the tips on all parts the interact with the gasket on the syringes, to better interface with the ones I have acquired. Remixed/Posted together to better fulfill the needs of a university assignment. Assembly instructions coming soon! Also included is a PDF with a sample lesson plan using this system. Print settings will vary from part to part, but in general a layer height of 0.2mm is best. Most will not need support. The Syringe Holder should have support placed only for the top of the part where there are overhangs that would otherwise begin printing over nothing.
