I really like this little Delta Printer and like the open source 3D printers. I made replacement part that is only two part the upper plate, and the lower and middle plate are fused together. The plates are ready to be made but the middle and bottom plate are upside down so it will print without bridges. PLA is not a good idea unless it high heat carbon fiber PLA or PETG that the Fisher can printer. If you print ABS just make sure that you make brim and raft. Both plates fit the RepRap Fisher with one print session.I really like this little Delta Printer and like the open source 3D printers.
