MAW-1 Mouse Droid

[kresty]

Working on the front wheels today.  Already have the back wheels figured out, but needed to get the front done.  MCK-Y used spray foam in the tires, but that didn't work terribly well, as you can see from the cut-out section here.  The foam cured unevenly, and then also wore some.

Damaged Spray Foam Wheel

The rear wheels were a pain to get the fit for the "inner tube" correct, because I couldn't see anything.  But I figured this wheel is trash anyway, so I cut a section from the tire.  I realized I'd also then be able to put that on the scanner.  I fairly quickly corrected the profile and ran a test print.  It fits good enough the first try!

You can see my cross-section of the tire and the printed inner-tube fits pretty well on the wheel.  (the right is a little more gapped because I printed it on that side, and had to leave slope so it didn't need supports).

Section of new "innertube"

Now I'm printing a full "inner tube," which is something like a 6 hour endeavor.  You'll notice that there are hollow cores within my "tube" to help make it squishy.

I bought another used FF printer, which is good because the first one is acting up a bit recently.  The used printer had a few issues, however I was able to get it running.  I'd tried the Ninjaflex a tiny bit when I first got it, but the temperature wasn't high enough, so I couldn't load it.  This time it loaded and printed first try!  

Fingers crossed that the printer keeps behaving as I have several inner tubes to print.  4 fronts for both droids as the rears are already done, and preferably a couple spares.
