3D modeler w/ 3D printer needed for opensource project

Working on an opensource project which uses stepper motors, the stepper motors used are super cheap and perfect for the projects requirements although they come with some housing which requires a custom part to be built, size of the part to be built is roughly 15mm x 10mm.
This is not a paid gig although I am able to provide a few copies of all the projects hardware & code parts needed for you to prototype which includes a few motors, screws, perspex sheet, wires etc.. I would say the difficulty of the part required to be built is Easy. I do not want to share specifics of the project just yet and understand that seems a little 'not-opensource' but if you are interested in being a part of the project please PM me.
