Watch Metroid Marathon 3 from August 31 to September 3, 2018. They are working with Extra Life to support the Children's Miracle Network Hospitals!
Here's a toy I designed for this event. I'm sending all of the Metroids pictured to the marathon! (I'm keeping my Samus Returns Amiibo, though.)
If you enjoy this design, please make a donation! Tell them Pikafoop's Metroid Spinner sent you in the comments. If you're not sure how much to give, I recommend $3.00 as a good starting point. (Or $3.14 if you're feeling nerdy.)
Sliced with Slic3r, using Archimedian Chords infill on top and bottom surfaces of the main body and bottom of the caps, Concentric infill on the top of the caps, and Rectilinear infill on other layers.
For part of the process, I had trouble getting the fine details of the teeth to stick, and had to add an outside brim.
I used 3D Solutech Silver Metal PLA for the prints shown. I used Xike 608-2RS bearings, and I'm very happy with their performance.
If you need to adjust the size of the model in your slicer, use the "608 Bearing EZ Mount" part to print just the center that touches the bearing.
Even though I use offsets to make it easier to place the 608RS bearing, it's still a tight fit. I line up the bearing and then press it into place with a couple of pieces of treated lumber, so I can put my weight into it. Pressing with a second bearing on top will sometimes help, if it's a particularly tough fit. Once the bearing is in place, it can be re-adjusted without too much effort.
