Lava Shield

My son is always on about needing a 'lava suit' when we walk in the parking lots, as a game about not stepping on parts of the road.  Lately, he complains that he forgot it upstairs when we get to the garage, and asks me for a 'temporary' (an idea I had one time to stop him from trying to bounce between lines).

So, as a surprise for tomorrow, I made him a real temporary.

This is two pieces, each about 4cm in diameter, printed in Grey v2 on a Formlabs 1+ printer.  Each has a cavity for a small natural magnet which is glued in (the magnets fit perfectly, but if you don't glue it in, the magnet might eventually come free.  Both pieces were printed simultaneously, and took about 1.5 hrs.  I then sanded a few rough spots from the supports, and post-cured it in a UV tank for 10 minutes.  I coated them with a single pass of red Rustoleum paint, followed by a single coat of acrylic coating for additional shine.

Now, I just need to keep myself from mentioning it until he brings up lava tomorrow morning...

Test printing the octomax

This is at .4 scale, so Amy errors are due to the difficulty in finishing the surface or notreaking it. I scaled out without modification so certain parts were just too flimsy.

Successful though, so I'll start the normal printing tomorrow. 



Working on a more sophisticated octo max suit

Printed at .1 

Printed at .1 

First test part print for a more sophisticated version of the octomax spot from octonauts.  Unlike the official toy, this will feature fully articulated joints. Here you are an arm.  Notice my silly mistake orienting the elbow to the shoulder joint. Obviously I'll fix that. 

More interesting is the hands attachment. Instead of one hand, my son will be able to screw in multiple hands just like in the show, including a grabber and a jackhammer, as well as an articulated hand.

The real toy has  batterieshich ist idiotic: you can't bring it in the water. The joints here are all plastic, so it will be water safe.

Obviously it will fit standard octonauts into it.
