Alright, I have fixed thumb4 problem to thumb5. I actually have no idea why it became bigger and couldn't fit wriargeV3 anymore. But I can't seem to upload it to thingiverse on the moment. It's been three days. I am located with a very poor internet connection at the moment. Hope this won't be long. Be patient, or if you are so desperate, go to thingiverse and send me your email, I will return you the STL.
