Filament Roller for 10x19x5 bearings and 10mm carbon rod

thingiverse

## **Materials Required** ## * ~8.5M of Filament * ~2 Hours Print time, depending on speed of printer * 4x 10x19x5 Bearings (I'm using 10x19x5 ZZ) * 2x 125mm L x 10mm W(OD) Carbon fibre / Metal Rod ## **Why?** ## I wanted a spool roller that I could make using bearings and parts I already had laying around. My spools are all different sizes. I needed something easy that I could easily swap spools around as required. I also wanted it one piece as I find lining up two sides annoying. Some of my RC Helicopters use 10x19x5 bearings in the blade grips, and after a crash they can get a little "notchy" when side-load is exhibited on the bearing. They are too good to throw out (Maybe I'm a hoarder?) so I keep them to be re-used in other applications. The Carbon rod is used as bracing material that is used in RC Helicopters for the tail boom. ## **Method** ## 1. Print the base in your desired filament. 2. Test fit the the bearings into the little curved slots - They should be snug and not fall out when turned upside-down 3. Remove the bearings from the frame 4. Feed one bearing on each side of the 125mm length of rod - The bearing should slide on with minimal force. The rod should NOT protrude out of the other side of the bearing. You may need to chamfer a small ridge onto the rod to make it easier to insert into the bearing. 5. Slide the completed bearings and rod assembly into the holder base. 6. Test that the rod rolls smoothly and evenly - If there is a wobbling effect on your bearing then the bearing is not straight on the rod, remove and give a gentle tap on a desk to assist in leveling.
