This is a remake of a useful dowel jig i found on thingiverse, with some little update
It allow to ease doweling on 15mm or 18mm plywood.
I also make a sled to easily align several jigs.
You can find my Fusion 360 file so you can create your own thickness and hole size editing parameters too.
The author marked this model as their own original creation. Imported from Thingiverse.
