BLV mgn Cube bearing fix

thingiverse

Yes, my print quality improved after making these changes. As I was putting my BLV mgn cube together, I ran into non stop bearing problems. Its really hard to work on because of all the washers. I couldn't take it anymore. Made some adjustments. 1. I removed all washers. Its so hard to get those washers in and out. In my design, the bearings fit without washers. I do not put the washer in the middle of the bearings, no idea why he does that. (Note, I kept the washers in the motor area because they are easy to handle. My sandwich was: 2 washers, bearing, bearing, 2 washers) 2. Changed the bolt on the X_Mount to come up from the bottom so you can easily remove bearings without them falling on the floor. The top plastic part can be removed while the bearings and belt sit on the bolt. Much cleaner when adjusting things. 3. Tensioner has a nut to put a little pressure on the bearings to help prevent them from tilting under pressure. My design helps address the bearings not sitting right in Mr. BLV's mgn cube design. I found a flaw where he has a .4mm gap in the X_mount on two of the bearing area's. This can be accounted for easly with a washer if you find it. But like most, its not easy to see. I solved that flaw by putting spacers in that are to the correct height. The belt will now ride true.
