Sewer Lair Reissue Conversion Kit

VAPOR SMOOTHED BY HAND FOR A PREMIUM COLLECTOR DISPLAY FINISH

Petranek Designs brings you the Sewer Lair Reissue Conversion Kit — a handcrafted, small-batch accessory kit designed for collectors who want to connect an 1989 compatible Petranek Designs Sewer Lair Expansion to the 2025 Sewer Lair Reissue.

The 2025 Reissue changed the connection points from the original 1989 Sewer Lair, which means 1989 expansion pieces may not line up correctly with the newer release. This conversion kit swaps out the key connection pieces so your compatible Petranek Designs Sewer Lair Expansion can connect more cleanly with the 2025 Reissue.

Each conversion kit is printed, finished, vapor-smoothed, inspected, and packed by hand by Petranek Designs.

Do You Need This Kit?

This kit is for collectors who already have a Petranek Designs Sewer Lair Expansion made for the original 1989 Sewer Lair and want to adapt it for the 2025 Sewer Lair Reissue.

• You now want to connect that expansion to the 2025 Sewer Lair Reissue

• You are using the original 1989 Sewer Lair and you are not trying to connect an existing expansion to the 2025 Reissue

Compatibility

This conversion kit is designed for use with the 2025 Sewer Lair Reissue and compatible Petranek Designs Sewer Lair Expansion displays.

This listing is for the Conversion Kit only, not a full Sewer Lair Expansion.

Original 1989 Sewer Lair, 2025 Sewer Lair Reissue, full expansion dioramas, figures, accessories, and other photographed display pieces are not included unless specifically listed in “What’s Included.”

Materials and Finish

This is a 3D-printed collector display accessory set made from filament and post-processed by hand.

Parts are trimmed, cleaned, and vapor-smoothed to greatly reduce the appearance of layer lines and rough edges. Because each item is made and finished by hand, small variations from the photos are normal. Minor surface variation, small rough edges, and slight finish differences may be present.

Collector Display Notice

This product is intended for adult collectors as a display diorama only. It is not a toy and is not intended for children. Keep away from young children.

This item may include small parts, sharp points, sharp edges, thin plastic parts, or fragile parts that can break if dropped, bent, stepped on, thrown, or misused. Handle carefully when positioning display figures or accessories. Do not force fingers into tight openings or use the product for climbing, sitting, standing, chewing, throwing, or rough play.

Inspect before use or display. Discontinue use immediately if damaged, cracked, broken, or if small parts become loose. Recommended for adult collectors ages 18+.

Made in Small Batches

Each Sewer Lair Reissue Conversion Kit is custom-designed, 3D printed, hand-finished, and packed by Petranek Designs. These are made in small batches, so availability may be limited.
