Doorbell button

thingiverse

Children as the engine of progress . I suffered a doorbell button in below to be more comfortable for children . Only then if the button was old , whether children were more likely to use it, but after a couple of months knob came off the wall and the base split button . So the question arose : the old glue button , go buy a new one or use the new machine and do it yourself . Matter of principle - do it yourself! So children have pushed me to study the intricacies of 3D modeling. Here is the result . In addition to the broken base, made ?the cover model and buttons . Now if you need a new simple doorbell button, you can print these three items, add the 3 screws , 2 strips of sheet metal ( copper, brass ) , spring-loaded button , cross- contact - a piece of wire or a nail , and the button is made . Screws under the wire 3x5 ( diameter x length in mm ), fixed cap - 3x8 countersunk screw cap . The spring diameter from 9 to 15 mm in a free state length of 7 mm. Transverse contact - a piece of wire or nail diameter 1.5 mm, length 18mm . Contacts based on plate - 5x18 should be fixed rigidly and not hang. The button should close contacts in the lower position . Enjoy. (translated by Google translator - do not judge for not literary language )
