Linear motion axis
cults3d
linear motion axis model. the previous model requires a worm screw of 4.5mm diameter. the desired length if you modify the length of the model, in this case 115mm. also two rods of 3mm diameter and for this case of 79.8mm long (guide rods of the CD or DVD drives). also the idea is to adapt to the worm screw a stepper motor and thus be able to give controlled advances. it requires a nut to insert in the 2 design as well as to rectify the holes. the design is simple to autocomplete with other designs that can be added with glue or screws. an example can be for the realization of a mini milling machine or mini rotor. the gear in the picture is not part of the model.
