I had this in mind a long time ago, unfortunately I lost the vector file.
Guide pair - two gas lift rods with a diameter of 6 mm and two brass fittings of the same internal diameter. The base is 10 mm thick getinax. The gas lift rods are glued into the base with epoxy. If I were to do this now, I would add a pusher attached to the engine with a water clamp. A red emergency button "Mushroom" would be suitable as the end of the pusher.
Next, I would add local illumination of the drilling zone. And, perhaps, I would add a magnifying glass.
All in one block.
