Wall drilling guide and dust extractor
Description
After using various drilling dust extractors for some time, i wanted something to keep the drillbit in place when drilling wall tiles (and walls in general). I made a drilling guide that can be used with usual impact drills (i did not tested it with a hammer drill, but i don't think the suction will be enough to keep the guide stuck on the wall with the increased impact force). It has a neck of 30mm that allow the use of a vacuum cleaner, for suction against the wall and dust removal. Also, the two windows allow placing the drillbit tip at the precise position for drilling. I uploaded multiple size guides because adjusting the center hole by drilling can remove the guide walls, unless you choose a higher infill percentage. If you use it often, with multiple drill diameters, you can print the largest one and the bushings for other diameters and then replace them when needed. A little bit of grease will ensure a longer usage for the guide and bushings. I used supports only for the center area of the guide. That shortened the print time with more than one hour compared with supports on the build plate for the entire object.
