- tinysensor_box.scad: wall-mounted box for PCB v2.2, screwed lid with gasket groove, int (vents) / ext (PG7 gland) variants - sensor_shield.scad: stacked-plate radiation shield for BMx280 breakout, wall bracket or snap clip under the main box - assembly.scad + rendu.png: overview render - README.md: export commands, assembly, hardware list, open points Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RNYLnB9ATL4uFdUmr9bSfN

…nder - tinysensor_box.scad: PG7 gland moved to the side wall by default (gland_side = left/right/bottom), under the flange chamfer; new part="open" render with the board inside and the lid flipped beside - stand.scad: table stand (mast screwed on the box wall ears + foot with socket) to stand box + clipped shield upright - sensor_shield.scad: shield shrunk from D80 x 72 to D56 x 52 mm (column 26, pitch 10, skirt 5); assembly/stand realigned - pcb.scad: simplified v2.2 board + 18650 from the KiCad positions - euro2.scad: 2-euro coin for scale in all renders - renders: rendu.png, rendu_pied.png, rendu_ouvert.png; README updated Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- mushroom.scad: amanita-style enclosure (in addition to the wall box): tilted, wavy superellipse cap screwed from below through the gill skirt, air gap above the roof; core with sensor chamber (BME280 and TP4056 in rails, micro-USB facing down), slotted gill skirt cut along the cap rim plane; perforated deck; hollow stem holding a vertical 18650 holder, ring and volva; glued-in dots - pcb.scad: board cropped along the silkscreen dashed lines (x=147, y=87) without the 18650/CR2032 holders; holder can be hidden - renders: rendu_champignon{,_dessous,_coupe}.png; README section Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- cap = dome + gill disc, set on the stem at 10° (tilted tenon in a collar); all electronics in the cap: chassis printed upright with the BME280 lying flat over the gill slots, perforated deck, cropped board, charger upright with micro-USB facing down between two gills; the stem only holds the 18650 - outline generator (lobe_seed/n/amp/top/rot): random harmonics, full at the rim and fading to the top, flat rim; clearance index echoed so any seed is checked against the electronics; dome tabs follow the lobes - tip: smooth (1-d²)³ bump on top of the dome, gentle on one side and steeper on the other, zero at the rim; dots placed by Poisson-disk sampling on the real surface - renders, seed board (champignon_graines.png), README Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- stem built as a polyhedron: tapered shaft with twisting lobes (adds material only, fades under the collar), asymmetric concave foot flare (<= 45°) instead of the volva bulb; ring swept around the stem with wavy overhang and drop, underside ~45° - ground: separate 1 mm lobed disc (D~115) to glue under the stem, with a zigzag grass fringe around the foot, curved grass tufts and single blades (0.9 mm walls, 0.6 mm tips) - generic harmonic generator (hterms/hval) shared by stem, ring, ground - renders incl. rendu_champignon_pied.png; README Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

All parts in print orientation, ready for OrcaSlicer; _xN suffix gives the number of copies. ./export.sh regenerates them (./export.sh stl for STL). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Bare cell held between two tab contacts (spring on -, dimple on +), no soldering on the cell; tabs exit through the floor into the flat where the wires run. Printed flat, no support. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

40 mm sealed chamber under the cradle (~30 cm³, ~140 g of 1 mm steel shot), conical ceiling printed without support. Filled through a 15 mm hole in the foot, closed by a glued plug in a counterbore. Cradle now sits 60 mm above the ground. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

2.4 mm wall around the whole flared foot instead of a 29.4 mm bore: ~52 cm³ (~245 g of steel shot) instead of ~30 cm³. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
