This tool builds the bird deterrent spike strip that mounts on walls, sills and fences, sized by you and exported as an STL. Enter the strip length and width in millimetres, choose the spike type and height, and the model is computed in your browser.
The strip is a honeycomb grid carrying staggered rows of pointed spikes. The aim is not to injure but to leave no flat surface to land on, which is why the spikes sit close together and offset row to row. The same template also makes wall caps against climbing cats and rodents.
Free, no sign-up. Change the sizes in millimetres and download the STL.
Each variant is the same template with different settings. Follow the link and the editor opens with those values.

A cone spike rises as a single point and protects from one direction, which is enough for large birds such as pigeons and crows. A star spike opens 5 to 16 arms that also spread sideways, which stops small birds like sparrows from working their way between the points. More arms widen the protected area but lengthen the print.
Screwed mounting puts a hole at each end of the strip, with diameters free from 2 to 10 mm. A 6 mm anchor with a 4 mm screw holds well in concrete and brick, and a wood screw goes straight into a timber fence. Since long strips have no middle hole, splitting them into 200 mm pieces and using two screws each is more secure.
The spikes are blunt-tipped cones with an adjustable tip size, not needles. They simply remove the flat surface a bird would land on, so the bird notices them and settles elsewhere. Keeping the tip above 1.2 mm both strengthens the print and reduces any risk.
Length can be set up to 400 mm, but most desktop beds are 220-256 mm. Printing 200 mm sections and laying them end to end is the practical route, and the panel reminds you above 250 mm.
ASA lasts several seasons and PETG one or two. PLA becomes brittle within months in the sun and the tips break when touched, so it is not suitable outdoors.
This tool builds a screw-on wall hook to your measurements and exports it as an STL. Pick a hook style, type the plate size and how far the hook should reach out in millimetres, set the screw holes, and the model is computed in your browser.

This tool builds the screw-on or adhesive base a cable tie passes through, sized by you and exported as an STL. Enter the base width and depth plus the slot width and length in millimetres, and the model is computed in your browser ready to download.

This page opens the DrawSTL L bracket template: a parametric right-angle corner bracket with screw holes that you size in millimetres and download as a print-ready STL. You give the horizontal arm, the vertical arm, the width and the thickness, and the holes are spaced evenly along each arm.
