UPDATED 4/6/17 - I had some complaints that the model was too small. I have resized it using the measurements give to me from a fellow "thingiverser". I also made some design tweaks. Let me know if this works better. Thanks for your support. please set your printer program to read the model in MM. The measurements I was given were 16mm x 16mm x 22.75mm. Special thanks to mothman92 for the help!The robo3d printer USB port has little to no support for a USB cable to hang out of. It made me nervous that it always looked like it was going to fall out or get bent by mistake, so I created this adapter. If you are using Repetier make sure to set the scale to 1.8. Thanks!
