Assembled with printed lock washers without need of screws - optional with motor upgrade. http://www.thingiverse.com/thing:468872 with replications ...on different 3D printers + latest STL file updates!
This Spider Rover can be simply clicked together with one and the same lock washer type. No screws required. Just in case you want to do more extensive research with it, you can add a motor. Pulley is in the files. The silver spider rover is 50% scaled down (not motorized), which needs the different named worm_gear_scaling.stl.
Be adviced that you have to be good in what you are doing when you start scaling down below 80% or if you add a motor to get it walking!
Printed on Ultimaker²
Cool
Minimal layer time (sec): 5
Enable cooling fan: yes
Occured problems:
UM2 feeder underextrusion through moved hobbed
pulley to the outer side on the motor shaft. Followed by slight ticking sound.
Moved hobbed pulley back about 2.5mm. Last step of filament change has to give you a hard powerful knocking sound when new filament
is coming out of the nozzle (before you then select PLA/ABS type)
Scaling:
For example crazy 50% - It's easier to scale all leg_pins_..stl to 0.48 for X/Y and Z=0.5 instead doing sanding. For 1:1 no sanding is required !
If you really have to do sanding - use a common nail file.
