Rokenbok Rack Base and Extender

These pieces are oddly named, they are the lift tracks used in Rokenbok for the Roklift (bin dumping elevator thing) and RC vehicle Elevator. Included are two models based on existing parts and one novel modification.

Rack Base is for RC elevators and Roklifts that start on the floor floor, and not a deck floor.
Rack Extender is for extending a lift rack and formerly could also be used on deck floors.
Rack Base Deck Cut is a Rack Base with the floor foot removed so that it can be used with the same offsets on a deck floor. It makes sense, I swear.

The models print with the gear track side down and require no supports.

All three models use a system I'm hereby deeming "Add a Snap," although it was first introduced on my Water Tower Spillway (Soup Bowl) model. The pockets on the backside function as regular snap pockets or can have an Add a Snap piece inserted to function like the original parts. Due to available material width, snaps can only be inserted in one orientation. A picture has been provided. When inserting Add a Snaps, hook one leg of the thicker side into the pocket, then press inward and down on the other side. The center of the part should bend slightly to allow it to snap into place.
