…wn work Panel-mount housing in three parts, parameterised, with every dimension read out of hardware/safekiln.kicad_pcb rather than guessed. Renders manifold, slices for PLA on a Prusa, and nothing has been printed. shell 54 x 81 x 115 mm, 8 h 49 m, open face up bezel 70 x 97 x 7 mm, 1 h 40 m, face down knob 25 x 25 x 16 mm, 27 m, bore up None needs support, which is a property of the geometry rather than of the profile: the shell's standoffs grow off its floor, the bezel's apertures are vertical walls, and the knob's bore is a hole going up. **The board's placement decided the shape, not a preference.** SW3, the rotary encoder, is ON the board at its left edge, and J1 and J2 are on that same edge. So that edge is the operator's face and the board stands on edge behind the panel, with the six terminal blocks on the right edge facing into the back of the box where the kiln's wiring belongs. Lying it flat would have put the knob on the side and the mains terminals on the operator's face. The first version of the model made the box as wide as the board's stack and nothing else, which gave a 23.4 mm front face for a 27 mm display module. It does not fit vertically either: that face already carries the DC input at y=11.1, USB at 23.9 and the encoder at 55.8, and the largest gap between them is about 25 mm. So the display takes its own lane beside the board's column, which is what a panel instrument looks like anyway. The render caught that before anything was printed, and the arithmetic is in the .scad beside `in_w`. **The knob** is for the EC11E's 6 mm shaft, printed bore up so the face the operator looks at is the one the bed made. Flutes rather than knurling, since a printed knurl at 0.2 mm layers is a texture nobody can feel; eight of them, findable with a glove on. The pointer is a moulded rib, not paint. **slice.sh checks four things that fail silently**, and three of them actually happened while writing it: A profile that is ignored. The first pla-0.2mm.ini used [print:]-style sections, which makes it a config BUNDLE: --load ignored it without a word and sliced at 0.3 mm, 200 degC and a cold bed, producing 891 kB of healthy looking G-code. The profile is flat now, and the script reads the settings back out of the finished G-code rather than trusting the file it passed in. A slicer that exits ZERO while refusing. PrusaSlicer rejected relative E without a per-layer G92 E0, printed the reason, wrote no file and returned success. So the existence of the output is the test, not the exit status. A duplicate key, which it does report, and a render that is not a closed solid or is too small to be the part, which it does not. Two hardware requirements fall out of the fit: HWR-24, the board has no mounting holes at all. The shell's four M3 standoffs are a proposal the board has to adopt, since the enclosure is parameterised and the board is not. HWR-25, 14 of 125 footprints sit outside the outline, including U4, the second MAX31856, at y=117.9 against an outline ending at 110. Both correct the task list, which also claimed the board had no tracks (it has 182 and 9 vias) and did not carry the supervisor (U5 is an STM32G031K8Tx, with both MAX31856 and the SWD tag-connect placed). A new section B carries the four things the enclosure needs before it can be screwed together. PLA is flagged as probably the wrong material: it softens at 55 to 60 degC and this bolts to a kiln's panel, which is what SWR-SAF-11 exists for. Print it for fit and feel; measure the panel before trusting it, and PETG or ASA slices from the same profile.

The board's placement decided the shape
SW3, the rotary encoder, is on the board at its left edge, withJ1andJ2on that same edge. So that edge is the operator's face and the board stands on edge behind the panel, with the six terminal blocks on the right edge facing into the back of the box. Lying it flat would have put the knob on the side and the mains terminals on the operator's face.My first version made the box as wide as the board's stack and nothing else: a 23.4 mm front face for a 27 mm display. It does not fit vertically either, that face already carrying the DC input at y=11.1, USB at 23.9 and the encoder at 55.8. The display now takes its own lane beside the board's column. The render caught it before anything was printed.
