Just thought I would share my latest homemade tool .
Where I work, we got a 3D printer. If you have used one of these things, you will know how useful they can be. You can design things from scratch to your exact spec.
Anyway, I am no 3D printer design guru, but I thought - tube support for pressing rockets! Even though it prints in plastic, they are incredibly strong.
After fiddling with Autodesk 123Design I exported my design and set it away printing.
I am really chuffed with how it has turned out. See for yourself below.
