Incident report · File 300‑R
Filed by the department that maintains land has no corners.
I. The brief
We were asked for a bigger base. We asked how big. The reply never came. In the absence of a stated limit, we concluded there wasn’t one, and proceeded on that understanding. This understanding has since been described, in the review, as “the root cause.” We dispute the tone.
II. The escalation
Progress was logged in millimetres, then in “surely that’s enough now,” then in a silence we chose not to break. A colleague raised a formal concern at 200mm. It was minuted. Work continued. At 260mm the same colleague raised the same concern, louder, and was thanked for their input. It was minuted again. The colleague has asked us to note, here, that they were right. We have noted it. We have not agreed to anything further.
III. Prior versions
Earlier attempts existed. A 250, and a 275. The 250 was destroyed in accordance with a policy we wrote immediately afterward, specifically to establish that its destruction had been correct. The 275 is a harder subject. It was signed out one evening and never signed back in. We have chosen to record it as destroyed, because the alternative is that it is still somewhere, and we are not equipped to hold that thought during working hours. No images survive of either. This too was policy — drafted, as ever, after the fact.
IV. The number
At 300mm the printer stopped of its own accord. We never established why. It had power. It had filament. It simply declined to continue, and we elected to read this as the design being finished. No one has since produced an argument strong enough to reopen the matter, and the printer has not spoken on the subject since.
V. The schism
Then came the question that ended working relationships: does land have corners? We are the department that says no. Land is a horizon. You do not walk to the edge of a field and drop off it — the ground curves gently away, as all serious ground does. We measured to the rim to be certain. There is no rim. We consider this closed.
Our former colleagues disagree. They hold that ground has edges, and that those edges should be paved. We no longer name them. Their version of this base is filed under 300mm Square. You may read it. We would prefer you didn’t. We are not, however, your supervisor.
VI. Attempts to establish purpose
Once the object existed, the question of what it was for became urgent, having gone unasked at every prior stage. A working group was formed. Its findings, reproduced here without comment, were as follows:
01 COLOSSAL MODEL. A base for the models nothing else will hold — the Titan, the large dragon, the scratch-built kitbash on its fourth base.
02 COMPLETE DIORAMA. An entire scene across one unbroken circle — a siege, a landing, a last stand that outgrew its table.
03 ENTIRE ARMY. Per a single report we have chosen not to verify, an army may be based upon it as one continuous piece. When your army is the unit.
Forty models. One base. One activation. No rulebook covers this scenario. Ours included. We checked ours specifically, then dissolved the working group before it could reach any further conclusions.
VII. The matter of the box
Shipping was raised late, as everything here was. The object does not fit in the box. It does not fit in any box we own. It ships flat, which is the single reasonable decision it makes, and it arrives as a circle of ground with no packaging large enough to have dignity. It won’t fit in the box. That’s the point. They told us it couldn’t be done. They were correct. We did it anyway.
It won’t fit in the box. That’s the point.
THIS. IS. THREE HUNDRED.
Notes · Q & A
What is the 300mm round base actually for?
A working group was convened to answer this. Its findings: (1) one very large model — a Titan, a custom dragon, a kitbash; (2) a complete scene or diorama built on a single continuous surface; (3) an entire army based as one unit. Models are placed on it, not painted onto it. The group was dissolved before it could reach a fourth use. We consider the three it reached to be plausible.
What’s the difference between Smooth and Textured?
Smooth is printed in PLA with a clean, flat top — ideal if you’re laying your own basing material, resin or scenery over it. Textured is printed in PETG on a textured plate, giving a fine, subtle surface that takes washes and drybrushing well straight out of the box. Both are roughly 6mm tall and black. The texture is, if we’re honest, the one claim on this listing we’re fully prepared to stand behind.
How do I prime and paint it?
Treat it like any FDM 3D print: a coat of primer first (rattle-can or brush-on both work), then acrylics. The textured surface holds a wash beautifully; the smooth surface can show faint print lines under gloss, so a matt primer and a textured basing layer hide those if you want a flawless finish. We recommend priming in a well-ventilated area. We recommend most things be done in a well-ventilated area, having learned this the hard way.
Does it fit in an OBS movement tray?
No. No OBS movement tray accommodates a 300mm base. We investigated manufacturing one. The feasibility study was filed under “do not.”
Is there a square version?
There is. It is filed under OBS 300mm Square Base, by colleagues who insist that land has corners. It does not. You are free to read their account — we simply ask that you come back afterwards.
Will it fit on my shelf?
It measures roughly 300mm (about 12 inches) across and ships flat. It will not fit in the box — that is the point. Several customers have reported building a new shelf. We are not able to supply the shelf.
