STL files tested on a Dimension 768 BST printer with support material ... OK!
STL files tested on a Ultimaker printer without support material ... OK!
- print out all 4 parts ...
- organize M3 and M5 allen screws and nuts ...
- organize LED and resistor for 9V, some wire and a jack ...
- I would suggest a 9V DC power supply with at least 2000mA current ...
- solder ... play ... have fun!
Do not try to build this adapter if you don't know what you are doing!
I shall not be held responsible if you burn your RCX, NXT or EV3 with incorrect voltage or bad polarity!
