Hubba Hubba v1.1 (Parametric & Customizable hole adapter)

thingiverse

In my DIY & maker escapades, there are moments when I simply need to get something spinning freely axially on a bearing. But for one reason or another, an adapter or hub is required to make the bearing work with whatever cylindrical object or hole I'm working with. Enter Hubba Hubba! Type in the dimensions you want for the two axles, how far apart they are, and how hollow you need the item to be. Boom! You've got it. But that's not all - this tool has other uses too. Need a quick funnel? Here you go! Want to make a custom reducer for a shop vac hose? No problem! Need to get a spool of solder spinning on someone else's solder spool holder? Okay, that one might be a bit obscure, but now you know where to look! The applications aren't limitless, but it's a fun thing to have in your toolbox. My first OpenSCAD file ever - a work in progress. Update Aug 24, 2015: I fixed the issues, but the code could use some refinement. Update Aug 17, 2015: A bug was discovered when using "Like a shell." The shallower the cone profile, the thinner the shell becomes. Not ideal - will fix it soon.
