About this model

Needed some terminal blocks but had to wait a week so made these. Each is set on a 7.5mm spacing so could fit on a PCB. Comes in two veriants, a single way connecto to be mounted on a PCB, and the common two way terminal block type. Prints in two halfs which slide to interlock to use with 8mm m2.5 or m3 bolt. Was desinged for a 1.5mm nut. Connection is by a piece of wire through the groove in the base. 0.6-1mm wire best. The end of which could also be solderd to a PCB. Printed on UP printer 0.2mm layer hight. Top might print without support if placed upside down. Most other details print ok but still may require some cleanup. Also includded is the step and 123d files if anyone would like to customise them. Happy Printing
