An assembly-free tool for maintenance of an engine in a vehicle is described. The tool comprises a bar extending in an axial direction and having a first portion with a first end and a second portion with a second end and a housing surrounding the first portion of the bar. The bar is axially translatable in relation to the housing. The housing comprises an embedded locking structure for holding the bar in a locking position to stop the movement of the bar in the axial direction. The bar, the housing and the locking structure are retained as one unit such that they are non-detachable from each other.

An example system for operation in a borehole in a hydrocarbon-bearing rock formation includes a logging tool for detecting one or more conditions in the borehole. The logging tool includes a tool body and a 4D printed sensing element. The 4D printed sensing element includes a 3D printed shape-memory material configured to alter in at least one spatial dimension in response to one or more stimuli, thereby generating a data signal. The example system includes a data recording device in communication with the logging tool to receive and record one or more data signals transmitted from the logging tool.
