Description

This morning I decided to check in on the current Kickstarter campaigns and featured as the project of the day was a mine detonator design called the Mine Kafon by Massoud Hassani. I was moved by Massouds vision for the project and general demeanor, and decided to design a 3D printed small model of the Mine Kafon, so here it is.

Short video: youtube.com/watch?v=_wE0XmCH5-E&feature=youtu.be

The main motivation is just to raise a little awareness of his project, which is to design a device to passively detonate hidden land mines and record their locations, so if you're interested go check out his campaign here:
kickstarter.com/projects/massoudhassani/mine-kafon?ref=home_spotlight

The model doesn't look exactly like his design and probably only has around half the number of feet (32 total). I think it turned out to be a fun little toy to play with and a pleasure to look at, hope you enjoy it too.

Instructions

Print quantity 1 of the Icosahedron parts and 32 of the Feet. Clean out the holes of the Icosahedron with a 1/16th inch drill (or 1.5mm or so). Get 32 toothpicks (the round ones, should be about 2mm diameter) and insert each into a foot with a dab of glue on the end, let dry, then insert the other ends of the toothpicks into the Icosahedron holes also with a dab of glue each. Depending on the fit of the toothpicks in the Icosahedron holes you may need to glue about 12 of the feet in at a time, let dry and then flip the Icosahedron so that the next 12 or so feet can be attached.

There are 2 options for the foot sizes - 30mm and 24mm. The 30mm's look a little better I think and the 24mm's roll better.

Both the 'FootPlate" STL's are for 100mm square build areas.

The mine kafon is an awesome project.

But now with that small version I'm tempted to make tiny toy mines out of rubber bands or something. I want to try it! :)

If you printed it as a shell, I wonder if it would be light enough to be moved by the wind...

I think so too. To me it seems the notion of a passive wind powered device would go better with a detector (instead of a detonator) and location recorder, since setting the mines off reliably requires some heft (from the little I've learned about it). One way or another I think the design has some very interesting aspects and I hope he is able to continue its development.

Some little spring-loaded mines would be super sweet! Maybe some little flaps to fit over the legs for a wind powered version?
