Just think of it as verticle trays.
Also chemicals will last weeks and weeks in the Nova, particulary if mixed with distilled water. I usually do my fiber stuff just after I've drained cleaned and re-filled it and then contiue to use it for weeks after to do my 10x8 RC stuff. Often it's the build up of silver in the dev slot that makes me drain it down. It should pay for itself in the long run.
If you got the fiber one doing fiber prints is a breeze once you get the hang of the holder. If you have one of the bigger quads you can still do fiber but may have to use two paper clips and take great care when moving from one slot to the next.
