Customizable Car Seat Gap Filler (Parametric - TrueGeometry Playground)

A parametric car seat gap filler - a long tapered strip that drops into the gap between seat and center console so phones, keys and fries stop disappearing. The loop end slips over the seatbelt buckle stalk; the slotted top is a catch pocket for your phone.

Honest limits: printed plastic is rigid, not the soft foam of store-bought fillers - it holds shape but does not squish into very tight gaps. Measure your seat gap and buckle stalk before printing. The 300 mm Standard needs a 250 mm bed on the diagonal; the 260 mm Compact fits 220 mm beds. Treat the first print as a fit check (PLA is fine for that, PETG for the real one). Print two - one per seat.

CUSTOMIZE - THAT'S THE POINT

This is a TrueGeometry Playground recipe: open it in your browser, change variables like $LEN (total length), $WH/$WT (head/tail width), $LPW/$BAR (anchor loop), $THK (base thickness), $POCK0/$POCK1 (pocket span) and $TSL/$TSW (tail slot), export a fresh STL. No CAD install. Tested presets: Compact 260 mm, Standard 300 mm, Long 340 mm (one-line preset switch included in the recipe).
