Type A latch 001 for 3D print 3D print model

It is a latch designed for 3d printing. In the prototype,I use rubber band to test. When you assemble the gadget, it is best to use a metal spring.You need to prepare some metal parts: 2pcs of small shafts, several M2 screws,a spring. Some hand job may be needed depending on the 3d prints quality.STEP format files are included. Ignore the STL, 3MF and AMF files, they are only for the platform's requirement. To open the PDF format file, your PDF reader should support 3D content. Of course, you can ignore the 3D PDF file too,it is only used to show you how to assemble the parts(you can get the information from the images too)
