A SYNTH CASE, MADE TWICE.

You can buy a eurorack case. You cannot fix one, change one, or cut a new panel for one when you crack it. Ada wanted the opposite: something she drew, cut on her own laser, and could remake from flat parts whenever the rack changed. So the first drawing was not the case. It was the plan for making the case, and the plan for making it again.

A laser cuts flat. So every piece of the case, the sides, the base, the inner walls, the corner brackets, gets drawn as a flat outline with finger joints and mounting holes, ready to cut. This is the part that pays off later. The drawing is the part. Re-cut the file and you have the panel again, exactly.

The first build went big. Two rows, finger-jointed sides, and a swing-bracket arm so the whole case could mount to a rear support and tilt up off the desk. It was a good problem to solve, and it stood up. It also flexed at the arm, and it taught her two things she could only learn by building it: she never once used it angled, and two rows was more case than her rack wanted.

A month in, the verdict was clear, and because the first build was written down, the second one was quick. One row. Flat panels and corner brackets cut from three millimeter clear acrylic. The finger joints stayed, the swing arm went, half the parts disappeared. She did not start over. She edited.

One row, full of modules, sitting flat on the bench with the side handles on. It holds what she plays, it is rigid, and it is the case she actually uses. The ambitious version was not wasted. It was the draft that made this one right.

A solo maker has no one to ask what the last version did. There is no teammate who remembers why the bracket was that thick or what the laser setting was. If the notebook page, the cut files, the photos, and the reasons for each change scatter across a drive and a phone and a workbench, the second build spends its first week relearning the first. Ada kept hers in one place. Here is the place.

The decision to drop the desk mount did not happen in her head and vanish. It happened on a board. What Rev 1 taught her in amber, what to change for Rev 2 in green, the decision in blue. Months later it still reads clean, which is the whole point. A solo maker's design review is with their past self, and that self needs notes.

The case is not three loose projects. Rev 1 and Rev 2 hang off it as parts of the same thing, so the iteration is drawn, not remembered. The notebook page and the rack photo sit in its media library. The work that started it is one click away. Open the case in a year and the shape of the whole effort is right there, revisions and all.

Under the visions is the actual sequence: sketch, draw the cut files, cut Rev 1, assemble it, decide it is overbuilt, redraw it as a single row, recut, mount the modules. Nine steps, including the one that mattered most, which was not a cut or a glue-up but a decision. The trail is the thing a solo maker can never keep in their head, and it is the thing that makes version two cheap.

The last thing she wrote was the thing that makes the case truly remakeable: the cut settings and the assembly order, in plain words. Which acrylic, which laser pass, dry-fit the finger joints first, fit the rails last. Crack a panel a year from now and it is a twenty minute fix from a document, not an afternoon of trying to remember.

The design, the cut files, both revisions, the reasoning, the steps, the photos, and the how-to. Not on a phone, a drive, a notebook, and a workbench, but on one sheet that holds the whole arc of a thing that got made twice. That is what a solo creator needs most and keeps least: the trail they left themselves. Plansheet is built to keep it.

A hardware build is only one of the things this table holds. A sticker run, a whole software product: each one starts as a why, earns a design, gets made, and ships, and each one keeps its trail. The case is the proof that even a physical thing, iterated by one person across two revisions, fits on a single sheet.
