SUK-A-BUG Vac Nozzle Extension

Collect stink bugs easily with this extension nozzle, a tube, and a Dyson® stick vacuum. - Uses a 19mm (3/4") tube, which is lighter and slimmer than the manufacturer's one and can be sourced in longer lengths. - A low-force non-return valve helps prevent bugs and odors from escaping. - An older Dyson is recommended. Short battery life is less of a concern because the vacuum is used intermittently, and bug collection can be a little messy.

TUBE - Find a round 19mm (3/4") lightweight tube, such as irrigation pipe or carbon-fiber tubing, at least 1.2m (4 ft) long. - Longer tubes provide greater reach but there is a weight and maneuverability trade off. - PVC conduit is available in longer lengths but is significantly heavier.

BODY - Tubes external diameter varies with wall thickness, therefore:- There are seven STL files for the body, with tube openings from Ø20.5mm to Ø23.5mm in 0.5mm increments. - Tubes with thinner walls are too fragile; larger ones too heavy. - Print the diameter gauge to identify the correct tube size, then print the matching body.

- The body prints in one piece, is already oriented correctly, and requires no supports.

END PROTECTORS - Seven matching end-protector sizes are provided. - Print in a rigid material and use tape to achieve a secure fit, or… - If printing in TPU, use a protector one or two sizes smaller so it stretches over the tube (that’s why there’s an eighth one that’s under-size). - A brightly coloured protector improves visibility and safety and is essential when using carbon-fiber tubes.

LATCH - Printing the latch on its side, as supplied, using small layer height and no supports, achieves the best surface finish. - If it refuses to stick to the bed, add a small brim.

VALVE - The non-return valve is an easy, flat print. - The arms have to flex during installation, making PETG a good choice of material.

ASSEMBLY - Take the spring from a retractable ballpoint pen and cut it 14.0mm - 14.5mm long. - Insert it into the body, from the tube side. - Insert the valve from the other side, with the recess facing up. - Before it is fully seated, pop the spring to the other side and ensure it sits over the pip. - Push the valve all the way in place until the arms latch into position and are straight again. - Cut a 6mm length off the same (or a slightly bigger) spring and use it for the latch. - Use self-adhesive tape to build up the end of the tube to create a snug and secure fit.

STINK BUGS Also known as bronze orange bugs and shield bugs, cause severe damage to citrus trees by piercing plant tissue and sucking out nutrient-rich sap. Types of Damage Caused - Tender New Growth: They feed on fresh shoots and young leaves, causing them to wilt, brown, wither, and die back. - Flower Loss: Feeding on flower stalks causes blossoms to wither and drop prematurely before fruit can even develop. - Fruit Drop: By piercing the tiny stems and stalks attached to developing fruit, they deplete the fruit of energy and cause tiny or growing citrus to fall off the tree. - Fruit Scarring & Smut: Their feeding punctures and presence can leave behind unsightly scars, discolouration, or stunted growth. - Caustic Fluid Burns: The foul-smelling liquid they secrete as a defense mechanism can severely scorch tender foliage, leaves, and cause skin or eye irritation to humans.

Scale of Impact - Young or Small Trees: Even a small number of bugs can rapidly stress, stunt, or nearly decimate a young citrus tree. - Established Trees: Mature trees can handle a few stragglers, but an unchecked, heavy infestation during spring and early summer can strip away the entire seasonal crop and significantly reduce overall tree vigour.
