BigCooter LM12UU - 12 X 30, 65, & 100mm Linear Bearing Mount

thingiverse

Generic LM12UU 12mm Linear Bearing Mounts, a new approach to building creations ... common generic parts mixed and matched as needed. IMO, a better approach than integrating too many functions into a single part that is used for only one application. The generic component approach also allows better design for 3D printing, orienting parts for build that avoids putting tension between printed layers during use (FDM printed parts are weaker in this way). These bearing mounts are FDM printed standing on end as shown, so FDM filament wraps around the bearing, so tighting the clamp screws will not easily crack the part. Included are some typical application uses of my own, for X and Z carriage assemblies for the soon to be released BigCooter 8X printer (450x450x450mm build volume!!!). This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/eYq2BQlAqJN Instructions Generic LM12UU linear bearing mounts, included is an example spacer for the 30mm long mount. Print the bearing mounts standing on end, this way the build layers will not be placed in tension when the bearings are screw tightened. My philosophy in designing 3D printed parts is to use multiple parts in order to reduce need for support material and to avoid placing build layers in tension (FDM printed parts can have low strength between build layers). Bearming mounts are designed for use with M3 screws, with slightly undersized printed holes ... to allow for drilling / resizing, and tapping or self tapping the M3 threads into the plastic (no metal nuts, I hate nut pockets).
