Center Marking Jig

A center marking woodworking jig I designed. There are two sizes. There are also inserts for drillbits/sharpie or a hex one for a pencil. I belive I used M4 hex screws to attach the center pieces to the bars. You shouldnt need any glue. The tolerance should allow the screws to screw firmly into the clamping bar but remain smooth for the center piece.

Print three center pieces and 2 clamping bars. Id reccomend also printing a few of the inserts.

PSA, the screw size is only a guess I made it awhile ago and do not remember exactly what size I used. Will update when I can check.

PSA 2, The insert are sized for drill bits but due to the nature of them being plastic they are not a long term solution and may not work well.

PSA 3, Print with greater than 2 wall thickness for a stronger jig.
