Thrust Bearing (6mm)

This is a thrust bearing for use in other projects.

Print instructions:

• Use PETG, 0.2mmlayer height (was clogging at 0.15mm with 0.6mm nozzle)
• Supports: off
• Infill: 60%,  gyroid (we want no crossings)
• Perimeters: 3
• Print all items flat side down, grove sides up
• Print 1x cage.stl and 2x top.stl sections (top and bottom are identical)

Assembly instructions:

• Use 6mm ball bearings - the cut-outs in the cage are +0.5mm offset to allow free rotation once inserted and have a sphere shaped void which you can only just see
• Balls press-fit into the cage, the give of the PETG lets the ball pass without breaking the plastic or needing some kind of bolt/glue together mechanism
• Place the ball bearing over one of the holes, cover with scrap of paper to avoid scratches and then squeeze the bearing into the frame hard with pliers. You will hear a distinct click as the ball passes the narrow part of the hole
• Repeat press fit process for the remaining ball bearings. If it worked you the balls should spin freely in the cage and you can shake it without the balls falling out
• The top and bottom races just sit above and below the cage, like a burger. They are not attached.
• The mechanism will be fixed in place by the fixture its installed into. Example: https://community.dfrobot.com/makelog-315681.html

Have lots of fun!
