    Finally, all four wheels are done.

    [​IMG]

    Next I need some rims, so I made a more detailed 3D model.

    [​IMG]

    Resin printed again to save some time in the post processing.

    [​IMG]

    Little bit of sanding and some spray filler and it was done.

    Like the wheels, I now will make a mold to cast the rims in resin.

    And it was time for the mold for the rim. This time a little different.
    To properly demold it at the end, I needed to split the mold in two halves.
    So I covered the first section with a little but of clay and added some
    registration marks.

    [​IMG]

    [​IMG]

    Mixed some silicone and poured it into the first half.

    [​IMG]

    After about 6 hours of curing, I flipped the mold over and added vents and
    a filling spout to the model. Then again mixed some silicone and poured the
    second half.

    [​IMG]

    [​IMG]

    Then I could cast all 4 rims in resin. Just need to take care
    of the flashing and then they are good for painting.

    That's not silicone! It's Greek yogurt! :(
    Lovely wheels, though. Even if they are made of yogurt.

    Wow. Those weels are a piece of art.

    Did you apply some kind of release agent to the silicone mold, before you poured the Smooth-Cast Onyx Slow?

    If so, how? It is a quite narrow gap to do it uniformly...

    Normally you dont need a release agent for this kind of resin.
    If i would use it for more than 4 castings, I would use some to extend the life span of the mold.
    I have Ease Release 200 which comes in a spray can. When you use a brush after spraying
    you can get it in almost any spot if necessary.

    Now that all parts are printed and cast, I can start building everything together.

    Started with the base. After filling all the imperfections, I followed it up with a couple
    layers of spray filler.

    [​IMG]

    After wet sanding, the base was primed black.

    [​IMG]

    [​IMG]

    Although, there will be only a tiny part visible at the end, I decided
    to paint everything. I dabbed on two layers of silver paint to get
    a little more structure.

    [​IMG]

    [​IMG]

    For a used look and to darken down the silver color, I applied a black wash to the parts.

    Next, I already started with the installation of the hardware on the base.
    Although the 3D print is stable, it got really rigid after mounting the
    radiator into place.

    [​IMG]

    [​IMG]

    The pump was mounted at the front. The fittings on top are just for decoration.
    Will see if I keep them after everything is set up.

    [​IMG]

    PSU got its position in the back.

    [​IMG]

    Cause I cant reach the in between space later on easily, I placed all cables and
    also the tubes for the water cooling already. Unfortunately, I needed the 90° fittings,
    cause otherwise it would collide with the upper section. Also a soft tube would
    bend to much.

    [​IMG]

    Then the next section was attached and screwed into place.

    [​IMG]

    [​IMG]

    Then I made a small detail for the site. Filled a tube with some coolant
    and attached it on the under side next to the radiator.

    Love it. :D I'm surprised none of us have built a Mars rover yet... A real one. Maybe this is the wrong gig.
    Also, Holy hell that pump is a fatty.
