This design is to suit the original filament mounting pipe that comes out the back of the machine at 90 degrees.
So far for me it has allowed me to retain the more compact spool mounting setup but be 100% tangle free.
The key is in the filament 'valve'. It is designed to only allow the filament to pass through easily in one direction. This is a simple part but highly recommended with unassisted printing.

2nd that
lawsy - where can I can the case bushing for the filament?

From Zimmer62 on this forum. There is also a derivative on Thingiverse that extends out the back further.
I just have my spool feeding from the underside, I'm about 2/3 done with the 2kg roll and I haven't tangled once. Like the design though.
I also have mine feeding from the bottom. I built a PVC Spool holder that holds 10 spools of filament. I've printed from all the spools without an issue. I did print the bushing shown on Lawsy's printer from Thingiverse. I am thinking about adding some tubing from my spools up to my printer to keep the end of each of my rolls next to the printer so I can switch quickly.
Can you post some photos of feeding from the bottom?

No picture needed, just flip the roll over from the picture in the original post. Filament comes under the roll instead of over the roll, and lines up better with the hole in the doodle. I've had no issues so far after printing about 1.3kg of my spool.
We added a PTFE filament guide on our Solidoodle...3dcreationsllc.com/2012/10/12/solidoodle-upgrades-diy-filament-guide-tube-ptfe-tubing/

Impressive!
this works like a charm.
I got one of the wider, smaller diameter reels, and it kept coming off the side.
printed this and haven't had an issue since.
Lawsy rules.
I had my first issue with this one yesterday, I had noticed that deeper into my roll of filament the spool had a join with just 2 pieces folded to hold the filament together, at some stage one of the folds caught the filament and stopped it coming off the roll, i was using hole number 2 .. the cross bar with the 3 rectangular holes has snapped on the first hole.. then the Y axis skipped about a half inch of steps, so a fair bit of force involved.
will print another one shortly, just thought I would mention it could maybe be stronger but I sort of like the idea of having a filament fuse.
Finally had my last of filament unwinding then binding at the spool. Just printed this out tonight and it's an absolute must. Can't believe I waited so long to do this. Fortunately I had small screws on hand from another project I'm working on. Thanks lawsy!
Lawsy,
I printed your filament guide to prevent the annoying crazy unwinding my filament does when I retract it out of the extruder. I also have the your take on tek's jigsaw replacement installed. I'm extremely happy with how both came out. Thank you so much! I do however notice my filament right at the top of the jigsaw replacement bending(when extruder moves forward) after installing the filament guide. The tension is causing my blue filament to turn to a light blue/white. I haven't noticed any quality change in my prints but I am nervous the filament might snap mid print. Is your's doing the same? I might try changing the orientation of the guide to see if that helps. Let me know if this is normal or if you have any tips.
Thanks again!
The turning white is normal for the filament and happens any time you bend it even in the slightest. As for the guide, I find changing the angle at which it sits can alter the operation a bit, but haven't found the optimum angle. As the moment mine is sitting about 20 degrees from vertical.
I actually changed it to about 20 degrees from vertical last night after looking at your pictures again. Seemed to make the bending much less severe.
The valve worked very well for me. Needed to modify the components holding the valve and added a standoff to hold it at a fixed distance from the back of the printer. Thanks for sharing.
