3D print for domino connector drilling jig?

[Tom777]

Has anyone made a drilling jig to use instead of buying the Connector Drilling Jig BS-KVD15? Using a 3d printer, it seems fairly straight forward. I just need 4 connectors for a project and hate to drop $200 on the jig and drill bit.

If it's for a one time use on a small number of holes, a 3D printed one would probably hold up quite well. Anything more significant is where the metal guides become crucial to maintain the accuracy.

Are you going to try to save more money by not buying the Festool drill bit (KVB-HW D15 CE) as well? That's another $65 for a 15mm diameter cutter.

For 4 connectors, you can probably just use one of those portable drill guides with edge and depth stops.

When you draw the line for the Domino, draw it 19mm long. Put the brad of your bit on the tip of the line. Found a 15mm bit from Home Depot for $9.97. Use the time-honored depth-set trick with a piece of blue tape as a flag. Drilling depth is 8mm deeper than the centerline of the Domino (so the height setting). For 4, it isn't worth more effort. Drill a hole through a chunk of hardwood to act as a drilling guide if you want to ensure it is square. I have the drilling jig, but essentially did this (but with the Festool bit from the kit) because I was inserting the connector dohicky from the underside for a portable dance stage.
