Design Brief
A minimal, general-purpose 3D-printed rover platform: plain 8 mm-pitch / M3 hole-grid plates (the "breadboard for rovers") plus a motor plate with four integrated N20 stations.
caster-trike reference build assembled + driving -- needs finetuning. spec v3

TP1 SPEAKER
The tp1_radio_mini MIRRORED: 7-slot grille band up top over a shallow-recessed Gikfun 2" driver, honest real-size OLED window mid-face, Ø26 knob tucked right under it.
v1.5concept
floor-mounted USB breakout + rear-lid fat-cover port; fully-seating plug; both parts version-stamped; first body/lid print warped despite 5mm brim; CAD fixed to full bed contact and gated; assembly bench then showed a USB panel-cable/lid-closure jam blocker; v0.5 replaced the lid USB panel cable with a measured USB-C breakout; v0.6 corrected the wall-mounted OLED boss spacing from the generic ±11/±11 datasheet read to the physically fitted radio_enclosure pattern; v0.7 rotates/lowers the measured KY-040 footprint so the encoder PCB clears the OLED PCB in the front-face plane; v0.8 moves the speaker frame forward from 13.0mm to 8.5mm, uses M3x5 speaker screws, and lowers the OLED/module lane for soldered OLED pigtails; v0.9 fattened the OLED bosses; v1.0–v1.2 first pivoted the breakout to rear-lid bosses, which fouled lid closure (protrusions into the body); v1.3 relocated the breakout to the body inner-bottom FLOOR and ran the USB plug out through the rear lid, so the lid carries no protrusions and closes clean; v1.4 shifted the floor bosses ~6mm toward the lid after a bench print showed the male plug could not reach the female socket (measured 10mm too deep); v1.5 opened the rear-lid port into a straight recess sized to the fat USB-C cover (11.5×7.2 overmold, 7mm neck) so the cover recesses and the plug fully seats with zero gap, and stamped both body ("B v1.5") and lid ("L v1.5") with the auto-injected version. v1.5 geometry is gated CLEAN but UNPRINTED — reprint body+lid to validate full seating.

FE-03 — FNIRSI HS-02A soldering iron station
The FE-03.4a bench station for the FNIRSI HS-02A iron: a faceted cream base (brass-wool cleaner well + cable strain relief) with a bold orange drop-in cradle that holds the iron tip-up, plus a standalone two-tone tip quiver for spare cartridges.

Radio Enclosure
Two-box internet radio enclosure for the custom ESP32-S3 carrier PCB v1.1 — honest exposed hardware (open conical speaker opening, no grille), crisp rounded-corner boxes with a 1.5 mm front-edge chamfer.
v2.3in progress
v2.3 — modernization pass: anti-warp chamfer on both lids + JST-XH speaker-disconnect socket captured in the acoustic mating wall; awaiting print test

OK-1
OK-1 is a compact desktop controller: a 0.96" OLED on the front, a KY-040 rotary encoder/knob on the right, driven by an ESP32-S3-Zero stacked behind the OLED.

v6.1 encoder-fit fix after print feedback; software-verified, awaiting re-print
FNIRSI HS-02A Fe2
Agentmic
FE-01
A bench station for the FNIRSI HS-02A: a holder that cradles the iron by its cool body, tip pointing down over a base carrying a brass-ball cleaner, a sponge, and tip storage.
v1.0printed + fit-validated
first working print; 2026-06-07) — the iron seats well in the rate-A tapered wedge cradle; form + fit work physically. Remaining: stability (add ~170 g ballast + anti-slip feet) and thermal in-use test. The poor first layers were a bed-level problem, not the design.
TP1 Radio
Build a single-front electronics enclosure heavily inspired by the Braun TP1: a tall rounded slab, circular perforated speaker field in the upper-left, a horizontal front split line, a small top-right station-window cue, a lower-left…
v2.4in progress
carrier spun 180° (USB-C exits the top); USB female thin-wall male-reach fix; controls at lower-middle. Reprint usb_lid_coupon + bench-fit next
TP1 Radio MINI
A minimized sibling of tp1_radio_enclosure, built to the same Gikfun 2" + S3-Zero carrier + KY-040 hardware and reusing every mount/fit verbatim.
v0.3concept
first mini assembly; bench fixes applied (USB female moved below the speaker, straps removed, larger anti-warp chamfers, USB-screw countersinks
Skimmer Lid
A custom cast-concrete replacement lid for a pool-deck skimmer, made at home from a 3D-printed mold.

FNIRSI HS-02A Insert
Adapt the stock FNIRSI HS-02B stand insert so it fits Daniel's FNIRSI HS-02A soldering iron.
v4provisional
v4 reshapes both seats into clean tapers that parallel the stock profile (deep grip kept: body ~Ø20.9, nose follows stock); simplifies the geometry off v3's imposed cylinders; awaiting a print + fit-test of v4
