The New Hotness

  • Onion Maggot Fly Sticky Trap Repair

    One of the sticky traps absorbed a mighty blow during the season and its ski-pole mount snapped off. Rather then rebuild the whole thing, I decided to just epoxy the pieces together and stick a reinforcing plate on the bottom.

    I added a pair of screw holes to the OpenSCAD model and produced a projection of the bottom layer:

    if (Layout == "Projection") {
        projection(cut=true) {
            Attachment();
            Cap();
        }
    }
    

    Which looked like this:

    Sticky Sheet Cage - projection
    Sticky Sheet Cage – projection

    Cutting that shape from an adhesive sheet looks the same:

    The somewhat raggedy large hole seems to come from OpenSCAD’s somewhat low-res SVG outline conversion.

    Fill the broken part with epoxy:

    Clamp it together on a plate to keep the bottom aligned:

    Cut an acrylic baseplate:

    Apply adhesive sheet to acrylic, stick it on the bottom of the cage, add a pair of stainless steel screws, and declare victory:

    We’ll see how long that lasts out in the garden next year …
