Tell us about yourself!
Happy you want to test it.One important point when you print the main part is to ensure a good fitting on the diameter 43mm of the drill. You can measure the exact diameter and adapt it on the 3D file (use the STP file), take in account also that your 3D printer will print a smaller hole.
It seems my explanations were not clear enough !It's a kind of portable drill press to use on any flat surface. The drilling depth can be adjusted.You can also add a vacuum cleaner with the adaptor.
I will add it soon in Thingiverse. The files are already available in the step 2.
