Vertical Filament Parts Drawer Remix - Double Bin Bonus Edition (OpenSCAD)

prusaprinters

I am very impressed by the original project.  I like working with OpenSCAD very much.  As a half-decent programmer, I appreciate all the hard work that led to this print.  Because the code was well-written, it was much easier for me to attack it with a rusty wrench.Full disclosure: I watched a video on YouTube on how to remove rust from old tools before I began, so this is a bit of an exaggeration.For tips on how to print this, see the original project.  This hack merely adds the option to print a longer bin.  This could be extended to perhaps a triple-height if one wanted to do that.  It would be fairly trivial to take my hack further.Be safe out there, it's a mad, mad world.March 5, 2022: Bug found by 3D Tiger in version 1 (see comments).Plan B:I revisited the slots and changed to what would be called a “sector” if the object were a circle.  I'm not the best with geometry terminology.  I just made one big slice to….  uh, oh….Okay, that didn't work, either, for the same reason.  And I just did all that math (nothing crazy but I'm rusty).  So I guess if this is to be done, the spokes of the wheels have to be reduced by two or one has to break out the scissors. Plan C:I changed the step in the for() loop from 1 to 2 to skip every other spoke in the wheels, and removed the pie wedge / second slot / second lock slot / peg in the bins, and it looks better.  Still untested as of March 5, 2022 but I'll try as soon as I can.Results:After the version 1 print finished (it took about 5 hours at 0.24 layer height on my machine), I tried it out, and it actually fit well!  I was using an Overture 1 Kg plastic spool, and it has a fair bit of flex / wiggle room.  I barely pushed it in and the guide wheels engaged and it held just fine.It did not, however, slide out freely, but perhaps in this application that is okay since you don't want 200 M3x5 screws bouncing off a concrete floor!What I mean to say is, you have to give it a very slight tug to get it out, but it stays in if you hold the spool upside-down.  So maybe that's okay.Plan D: Let the User decideOne can choose “Single”, “Double 1 Slot” or “Double 2 Slot” for the Bin_Type and see how they roll. ("Single" is the original).  If “Double 1 Slot” is chosen, the wheel guides have 6 spokes and the others have 12 spokes.  I like the “Double 2 Slot” option myself as you can mix and match your bins with standard 12 spoke wheel guide.Choose your own adventure. (Who killed Harlow Thrombey, anyway?) Changes:March 6, 2022 – Version v4: Slightly enlarged guide wheel spokes and slots for the “Double 1 Slot” option for more strength.March 10, 2022 – Version v5: A couple of math errors were fixed (angles and one x_offset).  General refractoring.Note:  I have been working with an Overture PETG 1 Kg plastic spool that I received in 2021. My measurements are not quite accurate (I'm looking at you, Inner_Spool_Diameter).  Don't take them as gospel!
