Hinge and fastener

thingiverse

After seeing these two fantastic projects on thingiverse.com, which bring joy to sick children, a group of makers in Zaragoza decide to replicate them for local hospitals. They are Pepo Jimenez from Madrid and Pablo Rubio from Zaragoza who printed both designs and showed them to medical personnel. The personnel told them that the boxes need to be bigger to accommodate the size of the bags they use. One idea to accomplish this on regular-sized 3D printers is to have external hinges that maximize space in the printer for the box. So, I designed these hinges and fastener as a proof of concept. Not yet sure if these hinges will be used for this, but they need to prove their robustness and size. They can be useful for other kinds of boxes. The minimum wall thickness is 2.5mm, but it can be thicker. The photo of the yellow wall shows an example of 5mm. Be careful with the direction of the hinges to avoid dismantling the box when opening. There are symmetrical versions, so use one of each. The file Hole.stl contains a hole that needs to be made in the wall to fit them. It is 0.25mm bigger to avoid problems.
