Scratchbuilt 18mm Scifi Desert Buildings

Hello again all,
Some years back, I was about to throw away a large piece of packaging EPS when I noticed that it had squarish holes which could be used to make something. I painted the inside of these holes with acrylic paint & sprayed expanding foam in them. The acrylic didn't serve as a release as intended & I had to break of the packaging but I was left with 5 squarish pieces of hard foam.

Last week I was looking at them , musing if I should throw them away ( too much stuff /ideas, too little time , as a usual)  & this idea came. Using packing carton shapes for fruit cut into roundish shapes & matchsticks I did this ( 4 to go ). Extras are 3d printed or card.

And now they are 5. In the last pic I put one used for melons on top of the 3. Quick, differently nice & effective .

Thanks for your comments. Z


  1. I have to admit when I first saw that packing carton thing I had no idea where you were going to go with it, but it turned out surprisingly well!

    As a side note, I'm yet to find something to act as an effective release agent with expanding foam. Vaseline worked well, but then you have the problem if it impregnating into the foam once it's cured.

    Anyway, enough waffle. Great job on this pretend building mate. Well done!

  2. Hey Mr.P,
    Good to hear from you. Thanks, Yes they did come quite nice. I have yet to try a wax based release agent. Though truth be told Vaseline can easily be removed by using turps or hot water ( if the model can take it. )
