CROW & BIRD REPELLENT FOR BALCONY RAILINGS
Here is a simple solution to get rid of crows and other birds which perch on your balcony railings and wake you up early in the morning with their noisy voices or dirty your balcony with their droppings. With these clamps, I ensure you that they cannot land on your balcony railings any more :) • Easy to print • Simple to mount/unmount • Environmental friendly • Minimum visual pollution • Easy to clean
There are two kinds of clamps: quadrangular and rounded. • Quadrangular clamp is standard and fits your quadrangular railings with a height between 2-3cm and a width between 3-4cm. • I have designed 7 rounded clamps for different diameter sizes between 3cm to 6cm for rounded railings.
You can "uniform scale" the whole parts at any slicer or CAD program for other railing sizes.
Bolt is standard and designed to fit every clamp quadrangular or rounded (for every size).
Mounting: Just print 4 pieces of each clamp and 4 corresponding bolts and mount them at the beginning and ending edges of the railings and 2 for each corner. Stretch the fishing line (#) between them using the holes on the clamp sticks and that's all. You can use one fishing line and pass it through the holes of the clamps beginning from the top holes and reaching to the bottom; moving down step by step at each turn (see the pictures). (#) Instead of fishing line, you can also use thin wire or similiar material yarns, thread, string etc. strong enough against weather conditions and corruption.
Printing Instructions: • Clamps and bolts can be printed with 0.28mm layer height without any support. • Infill for clamps is >=20% and for bolt >=80%. • Printing materials are PETG or ABS. DO NOT USE PLA, as the sticks may melt in hot weather. • After print, lubricate the bolts with dry soap for easy screwing.
Happy printings :) Botcan3D
