About this 3D model

Prototype spool mounts for MendelMax Most likely not the final version, I certainly welcome comments for improvements! Version 7! This version works pretty good. This version is a bit longer resulting in a more stable base for the spool. There are holes for #5 screws, but you don't need to use them. There are also holes to hold the bearings to the mount, but again you don't need to use them. Notes to me: consider making inner bearing hole a touch smaller, so it grabs #5s without needing a nut. Consider making shoulder a touch taller, so bearing has no chance of rubbing on the body of the mount. This configuration is gripping the frame very well without a bolt and remains easy to reposition - probably final version, don't mess with it! It works well.
