Cricut Maker - Roller Clip

The roller on the Cricut Maker has a tendency to start moving after some use. This little clip rests beside the roller and slots into the groove on the metal bar thus ensuing the roller can not easily move. Initially inspired by the model by MrMark J but his original STL would not print for me. So I simplified it and removed the need for the metal wire as I didn't trust that it would stay in place for me and if it fell out could cause damage to the cutter. So far it works well for me :)
