Self centering dowel jig

EDIT 17/02/2020 : I uploaded all files separately. All with V10 version number.
Here's the list and some infos :

- Body V10.stl : the main body. Prin it solid, with at last 8 walls and 40% infill.
- Side panels V10.stl : they're 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 on two parts in your slicer, it will be easier to print. And use it like a unique piece, no prob with that.
- Spacer - bearing 30x10x9 V10.stl : the original one for 10mm drill.
- Crosshair V10.stl : removable crosshair to align the tool on your mark.
- Self centering dowel jig V10.3mf : 3MF file containing every file above, including splitted 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 2 bearinbgs you'll choose) is 29.4
