I built a Prusa Mendel RepRap printer from a kit sold by MakerGear. It took me 22 days working about 2-3 hours every other day to assemble the kit to a point where I can print parts. I still have some wire management to sort out, and I’ll probably eventually build a cabinet for it, but the basic printer is finished after around 25 hours of work. Here is an animated gif I made of the time-lapse photos of the assembly process.
My first print was a teardrop (the RepRap logo) shaped shot glass by raldrich.
Next up….printing all of the cool additions, upgrades, and add-on’s for my 3D printer, plus a box of spare parts.
