Even with the cost of 3D Printers continually falling, entering the hobby still requires a significant investment. [Skeat] had some typical 3D Printer components available but didn’t have access to a printer for making the ever-so-common frame parts of typical RepRap designs.
[Skeat’s] plan was to cobble together a printer just good enough to print out parts for another, more robust one. The frame is made from wood, a very inexpensive and available material. The frame is not screwed together and doesn’t have any alignment tabs, it’s just hand cut pieces glued together. Each portion of the frame is laid out, aligned with a carpenter’s square and then glued together. This design and assembly method was intentional as [Skeat] didn’t have access to any precision tools. He stated that the only parts of the frame that had to be somewhat precise were the motor mount holes. The assembly process is well documented to aid anyone else looking to make something similar.
In addition to the wooden frame, all of the components are glued in place. That includes the bearings, rods, limit switches and even the Z axis motor! After seeing the photos of this printer, it would be easy to dismiss it as a poor performer. The below video shows that this printer’s print quality can keep up with any hobby level machine available. We wonder if [Skeat] is rethinking making another since this one works so well.
