Internal Bore Spatula

Please design a 3D-printable internal bore spatula for applying putty inside a Ø3.000 in bore, targeting the inclined rod area approximately 12 in from the left opening. The complete tool must fit within a max Ø2.85 in clearance envelope. Recommended 3D-print dimensions: - Blade: rounded/curved profile, 2.60–2.70 in wide x 1.35 in long - Blade thickness: 0.100–0.125 in for strength - Tapered leading edge: reduce to about 0.040–0.060 in - Blade working radius: approx. R1.30–R1.35 - All edges rounded, no sharp corners - Handle: Ø0.500 in round or 0.375 x 0.500 in oval/rectangular section - Handle length to blade: 13.00 in - Grip length: 5.50 in - Overall length: approx. 18.50 in - Blade/neck angle: 45° - Add fillets at the neck/blade joint, minimum R0.25–R0.50, to avoid snapping during use Material suggestion: PETG, nylon, or reinforced filament if available. Avoid making the blade too thin because a 3D-printed blade may flex or break.
