Dowel drilling jig

Remix of Kuhes doweling jig. In original the bearings keep being pushed or puled out so I decided to remixed the jig the spacer and bearings get inserted during print.

There are 2 pauses 1st to insert the bearings and spacer and second 2-3 layers later in order to clear the filament which does not stick on the bearings after print is resumed on first pause.

modified it to hold the bearings in the jig. On original design they always kept being puled out by drill.
