The idea was for children aged 10-12 to create materials which could be easily assembled into new objects during Code Club meeting hours. The Code Club is a weekly organized, Wednesday afternoon meeting at the local library where children are encouraged to be creative. The children are involved with using a 3D Printer, a 3D Pen, programming small robots, making music with fruits, and lots of other ideas (including this Meccano idea).
When the project came along my first thoughts were about Meccano. A toy from my youth which consisted of metal strips and bars. Because of the development of Lego's and Play Mobile the metal Meccano disappeared. But I felt that Meccano is still a great toy which is allows children to play and learn about the basics of constructing and gain some technical skills. Because we all hear on the Dutch news technical educated people are in high demand I decided to start using the 3D Printer to (re)create the Meccano parts.

PLA (polylactic acid) filament is amongst the oldest and still the most heavily used mediums in the 3D printing community, mainly due to its benefits as a versatile and environmentally friendly thermoplastic. Both organic and biodegradable, PLA is easily compounded with other ingredients to influence its final properties. RepRapFilament prints best at a temperature of roughly 200 degrees.
The filament should extrude smoothly and the end result appear slightly shiny.
PLA can print well on an unheated surface using Blue Painters or Kapton tape, and most 3D print stickers. For ease and convenience, we recommend using spray such as 3DLAC  on a glass bed. A low bed temperature between 50 - 60 degrees further reduces the chance of warping and makes final print removal easier once the print surface has cooled.
