Proxxon MICROMOT 50 drill stand.
Not yet quite assembled, I'm still waiting for some parts.
I made some changes to 3D printed parts. I hope that this will now be finally done. Later, I will describe the assembly and other material that we need (screws, bearings, axles ...), and add photos of the finished product.
I made a bracket without LM8UU 8mm Linear Ball Bearing, only plastic bushings. You can choose between Ball Bearings (bracket.stl) and without bearings (bracket-WB.stl). With the bearings works much better, driving more smoothly and easier
At the drilling of printed circuit boards with drill bits of tungsten alloys, I always had problems with breaking of drill bits. Solution is stand for the drill, which can be expensive. Since I have 3d printer at home (also homebrew), I said to myself, let's do prefer to make a DIY stand. On eBay I found a linear bearings for a few bucks set, which I bought and added some of own stuff and that's it. I think the instructions are not required, picture says more. I took for the leads seamless stainless steel tube with a diameter of 8mm .
For questions I am always available.
Successfully making and drilling!
