Reviewer 1 Report
Introduction has mostly general content.
The whole paper has general content. The article describes one of the many applications of 3D printing for practical purposes. Due to its elaboration, I do not see any scientific benefit in the article, it must be added.
I have big reservations about the stated measurement of component dimensions. The authors do not report any accuracies, measurement statistics are missing.
I recommend overwrite the conclusion and complete the discussion of the results. It is very general too without more detailed description.
The references are adequate and state-of-the art.
The contribution is applicable for journal after revisions.
