Self centering dowel jig

thingiverse

I uploaded all files separately. All have a V10 version number. Here's the list and some information: - Body V10.stl: The main body should be printed solid with at least eight walls and 40% infill. - Side panels V10.stl: They are the legs. If needed, separate them in slicer and/or rotate them (25 degrees) to align them along the X axis. - Spacer - bearing 22x8x7 V10.stl: A new spacer made for 22x8x7 bearings (8mm drill). Split it into two parts in your slicer; it will be easier to print. Use it like a single piece, no problem with that. - Spacer - bearing 30x10x9 V10.stl: The original one for 10mm drill. - Crosshair V10.stl: A removable crosshair to align the tool on your mark. - Self-centering dowel jig V10.3mf: A 3MF file containing every file above, including the split spacer - bearing 22x8x7 V10.stl. You can make new spacers for your own needs. Just make them 29.8mm large and remember the whole cylinder you need to fill with it (and the two bearings you'll choose) is 29.4mm. You will still need two screws (M6x55) and rubber to protect your wood. ======================================== I added a file called "Gabarit de perçage auto-centré v7.stl" which contains two different legs to fix the jig with one clamp. (See the first and last pictures.) Not shown on pictures but I also added some rubber to the legs, to prevent damages on the wood. ======================================== I needed to drill a 10mm hole, 70mm depth. This will give you a 30mm high guide to drill without accidentally going outside of the wood. You will need two screws (M6x55) with nylon nuts and two bearings 30x10x9. The three little parts must be printed at 0.2mm height, and the main body must be printed at 0.3mm height.
