Kuat NV bike rack wheel tray end cap
The plastic caps on the ends of Kuat NV and Sherpa wheel trays crack in the cold and let water into the extrusion. This replacement cap is a rectangular plug with a 3 mm face plate, four 1.5 mm ribs that friction fit into the tray's hollow section with 0.2 mm interference, and a 5 mm hole for the original retaining screw. Dimensions come from the measured tray opening; print it face-down in ASA or PETG at 50 percent infill so it shrugs off road salt and UV.

Example prompt
Model a rectangular end cap for a 60 x 28 mm hollow aluminium tray with a 3 mm face plate 64 x 32 mm, a 15 mm deep plug with four 1.5 mm friction ribs at 0.2 mm interference, a 5 mm screw hole and 2 mm rounded outer corners.
Fit notes
Tray extrusions differ between Kuat, Thule T2 and Yakima HoldUp racks and even between generations, so a downloaded cap may be a millimetre off and fall out on the motorway. Measure your tray, tell SpeakCAD the opening size and screw position, preview the cap in the browser, tweak the rib interference in the chat, then download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
