Printed drilling fixture for angled holes

thingiverse

This is a fixture I made, to use on my drill press to drill a set of angled holes in a prepared blank. The clamping block also locates a couple of other holes that are drilled into or through the round blank before placing the clamp into the angled table. The through holes are used to fix the blank in place in the clamping block. I start each with a center drill, then complete the boring operation with a jobber drill. I use the final size drill in the drill press with a printed model of the part in the clamping block and table to locate the printed table on the drill press, then clamp it in place. The clamping block is pulled out of the table and rotated by one facet to locate all the holes after the first. Instructions The table and clamping block were printed in ABS without supports. (The 45 degree angle seems to be fine without supports). Marlin defaults on all other parameters. A .4mm nozzle, .2mm layers.
