thingiverse
The first thing I ever designed and printed!
There are a number of other space invaders on here already, but they're either small, or made to accept a magnet, neither of which fit my needs.
This invader is quite large. I printed it at about 70% on a not particularly well calibrated printer (it was only my third print ever) and was very happy with the results, so it should be good even for beginners.
Instructions
Print the file with the layer height and infill settings of your choice. I printed mine at .3mm height with 20% infill on my barely calibrated Solidoodle2 and it turned out quite nicely.
This is an extremely large space invader, I would recommend shrinking it in your slicing software before printing (I printed at .7 size and it turned out roughly the size of my palm).
