Filadelphia 1.0 (Please check out 2.0 instead)

thingiverse

Philadelphia is a freestanding filament holder that prints in one piece without supports on a Makerbot Replicator 2 with PLA. Everything is modeled at an angle so the wheels' axes spin and remain in place without assembly, additional parts, or screws : Just print 4 of them, unfold the stands & click them together. As proof of concept here's a timelapse of printing 8 Philadelphias (8 hours) ... fed by earlier printed Philadelphias : https://www.youtube.com/watch?v=_c32D4GcHnY Here you can see how multiple Philadelphias interconnect to put multiple rails next to each other : https://www.youtube.com/watch?v=oyPpUEeihMw Instructions Philadelphia was created from scratch in Blender and printed in PLA with Makerbot Desktop Beta 3.7.0.108. I found that printing at standard (0.2mm) resolution gave the best results. It takes about an hour to print one object and I can print 8 at once. Here's how it comes off the raft and unfolds : https://www.youtube.com/watch?v=gZvuMnsu6YY As you see, the wheels spin perfectly (and actually a lot better than I ever expected :) ). Although it stands on its own, I provided a screw hole for those who want to fix it in a more permanent way. With the pads folded inward, you can mount two rails closely together and save space. The pieces may feel somewhat difficult to click together but we prefer them secure and that didn't work perfectly with earlier (more loose) tests. I've added a 'connector' (removed the wheel & holder) to fit between two rails and a double version as well.
