After we Open-Sourced the design of Tinyboy 3D Printer, more than one manufacturer commercialised the design and sold a good number of printers with their own channels. More education organisations and individuals can now afford Tinyboy and take advantage to this new technology.
On the other hand, the design of Tinyboy 3D printer is released under Creative Commons Attribution-Sharelike licence and many manufacturers legally made their own modifications to fit their target audiences. We are not aware of the details of those changes and may not be able to provide the best answers to specific questions.
Any comments that we made is offered in good faith to the best of our knowledge, but they cannot be regarded as a substitute for the official customer support offered by the manufacturers. Moreover, Tinyboy acts as a neutral body to all manufacturers and we did not receive any monetary compensation to provide customer support on behalf of any manufacturers.
