Kitbashing

Kitbashing is a technique in scale modeling and miniature construction in which parts from multiple model kits or other sources are combined to create a new, unique model or variant. The practice allows builders to produce custom designs not available as a single kit, often by grafting components such as hulls, fuselages, or weaponry from different kits and then reshaping and detailing to fit a coherent whole. It is widely used in plastic scale modeling, resin or metal miniatures, model railroading, and tabletop wargaming.

Historically, kitbashing grew from hobbyists seeking options beyond standard kits and has been prominent in science fiction and film effects modeling. The advent of 3D printing and online sourcing of parts has further expanded the practice, enabling more complex or speculative creations.

The process typically involves planning a concept, selecting compatible parts, and aligning scales. Builders cut, trim, and modify attachment points, then assemble with glue or cement. Surfaces are reshaped and seams filled with putty or epoxy, followed by sanding and detailing to achieve a unified appearance. Finishing generally proceeds with priming and painting to blend disparate elements into a cohesive model. Common tools include hobby knives, files, plastic cement, super glue, putty, and abrasives; additional materials such as sanding sticks, clamps, and a rotary tool are often used for more involved changes.

Benefits include expanded design freedom, customization, and potential cost savings. Drawbacks can include longer build times, fit difficulties, and the need for advanced finishing to achieve a seamless look.
