If you've already printed everything from fhuable's Camera Gimbal and want to use 608 bearings instead of "6000 Series deep groove ball bearings", fear not. You haven't wasted (much) time and filament. With some slight modification to your M1x160 spur gear, you can use these adapters to implement 608 bearings in the build with (nearly) all your existing pieces.
Why you would use these:
If you want to use 608 bearings for fhuable's Camera Gimbal instead of the 6000 series deep grooves.
How to use these:
If you've already printed all the original files from fhuable's design, then you don't need to print the M1x160 spur gear on this page. Just remove the 8mm hinge pin from the M1x160 spur gear you've already made, using whatever means you'd like. I broke it off by force, but you could also file it down. Then fit the M1x160 Hinge Adapter over the raised circle that the hinge pin was placed on - it will be a tight fit but should snap into place with some force. It should look like the above image, with the grey hinge adapter on my purple M1x160 gear.
If you haven't printed the original M1x160 spur gear, then the modified version on this page should fit into your 608 bearings. In that case, you don't need to print M1x160HingeAdapter.
Next you'll need 4x "26to22mm Bearing adapter 2" placed in the bearing slots for main A, B, C, and D.
You will need to insert "M128Adapter" into the M1x128 spur gear, and these 8mm tubes can act as your main axis once cut down to size. (I used a cheap miniature hacksaw.)
Finally, substitute "CamLegHinge8mm" for the original camLegHinge, and you should be able to fully assemble the entire system using those cheap and handy 608 bearings.
