1:32 Bf 109K-4 Exhaust Stacks PRINT for Kotare

Eduard Bf 109K-4 Exhaust Stacks, 1:32 – 3D-Printed Stacks for the Kotare Kit

The set from Eduard is an accessory, not a model kit. It provides engine exhaust stacks for the Messerschmitt Bf 109K-4 in 1:32 scale, printed in resin with modern 3D technology. The parts are made specifically for the Bf 109K-4 kit from Kotare and replace its plastic exhaust stacks. You need the base model to build it — the set alone does not make an aircraft.

What the set is for

Exhaust stacks are one of the most exposed spots for the eye on single-engine fighters. Injection-molded plastic, though, cannot make them hollow: the mold cannot open at this spot, so the exhaust outlets usually come out blanked off. This set fixes exactly that. 3D printing allows for hollow, open ends of the exhaust pipes with a thin wall, along with sharp surface detail of welds and flanges. At the large 1:32 scale, this is a difference visible at first glance — and it does away with the tedious drilling out of plastic parts with a micro-drill.

Usage tips

• Carefully separate the parts from the print supports and casting blocks with a cutter or a fine saw; do not tear them off.
• Wash with water and dish soap before painting — residue of print resin worsens paint adhesion.
• Glue with cyanoacrylate glue; plastic cement does not bond with resin.
• Sand with respiratory protection, ideally wet.
• Create a burnt-exhaust effect with a dark base coat, metallic shades and a layer of brown-rust pigment or wash running back from the outlet.

Who the set is for

• Builders of the Bf 109K-4 kit in 1:32 scale from Kotare.
• Modelers who want genuinely hollow exhausts instead of blanked-off plastic.
• More experienced modelers accustomed to working with resin and cyanoacrylate glue.
• Collectors of large scales, where engine detail determines the overall impression.

This is an accessory for modelers, not a stand-alone kit. It is supplied unassembled and unpainted; the base model, glue and paints are not included in the package.
