3D print tips

All the stl file were attached in zip file. When you unarchive the zip file, you maybe find the file name end with number.
Download resources here.

Looking at the file name, if the file name contained "*3", that means this part should be printed 3 times. If the file name contained "need mirror", that means this part should be printed 2 times, and one should be a mirror part of another.

Step 2:

This is my main tool. since I can't find a M2 allen wrench head for this Bosch screwdriver, I cut off a M2 allen wrench, and insert it into the screwdriver. Lol...
notice the front side and the back size of the Leg A. Because the screws were axis for the Joint, these holes should be extended by a 2.1mm drill, to make sure the screws can cross the hols easily.

Step 3:

Connect Bottom and LegB, the screws should not be tight.
attach the Leg main part and Leg A parts. then attach the foot parts. Notice the difference between Foot A and Foot B, remeber to select a fit one.
attached Foot B to Bottom

Step 4:

attached the Leg C and Main Gear. Don't forget to extend the screw holes.
attached the main leg to Main gear. Notice that these three screws should not be tight.
notice the detail part

Step 5:

Attached all 6 feet, and this is back side view.

This is front side view.

Step 6:

Use the pillar to connect main gear and the bottom part like that:

Step 7:

Since the transmission shaft is too long, We cut it to 4mm.

And this is the spinning structure.

Step 8:

Connect two parts

Step 9:

Gear box part

combine them together.

Step 10:

Gearbox and frame

and Servo and Edison support

Step 11:

Camera and camera shell, since maybe you use different camera, so feel free to use the glue.

now you will get your own Xpider.
