I built this adjustable fence guide for most drill presses. Should bolt down to the bed with 8mm x 25mm or 5/16" x 1" bolts.

Stop blocks are designed to hold a 5/16" x 1" bolt, so only 1 wrench will be needed to remove and tighten them. There is a right and a left, and they have an offset hole so you can use them in different combinations to account for the brace in the middle of the fence.

I used 20% infill, with supports for the slot and the bolt hole in the stop blocks, very easy to remove support.
