In this paper the prototype of the device for field testing of the connection between reinforced concrete and anchor bolt was developed. Anchor bolts are often used in construction and mechanical structures or equipment to fasten them to the base: concrete, stone or some other building material. The basic factors that are important for the safe functioning of anchor bolts are the condition of the base, the operating load, the influence of the environment and proper installation. That is why it is very important to carry out adequate testing of the connection between the anchor bolt and the base after their installation, because this is the only way to make sure that they will perform their critical role. The paper presents the original solution of the testing device, which will enable the testing of installed anchor bolts in a wide range. The device enables monitoring of the most important parameters related to the quality of the base in which they are installed, the quality of the installation and the quality of the anchor bolt. The initial solution of this device was given, which meets the current technical directives and was validated by the Finite Element Method (FEM), in order to check the capacity under the static load and determine potential stress concentrations. The model was optimized in several iterations, using the Topology Optimization method, in order to obtain a lightweight construction, and the obtained results were compared with the initial model. The models are made using additive technology Fused Filament Fabrication (FFF), with the application of Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE). The device is ergonomically designed based on the operating load through the use of eco-friendly materials, optimization of mass and shape
