150g Flipper Battlebot

Flipper Robot. This is a 150g combat robot. I'm attaching the .STEP file as well for those who want to edit.

Very simple build that doesn't require many extra tools. Wedges can be printed or cut out of a sturdy material. 0.5mm Titanium is ideal. But Plexi/Acrylic also work as well. Printed wedges work fine if you're just flipping things around the house. There are two styles of top plates also, flat plate version or thicker angled prints

Assembly tricks: I used a lighter and heated the nails when inserting them into the printed arms. This creates a tight fit and keeps them from backing out. Otherwise a drop of superglue keeps them in the arms. The holes in the body and the hole in the lifter linkage should a loose fit for the nails so they can rotate freely. The nail spacers are put on the nail to keep the servo linkage from moving too much laterally on the nail.

I use a paper clip to attach the flipper to the servo arm and cut off the excess after its bent.
