Tent guy line tensioner for 3 mm reflective cord
A three-hole line tensioner for the 2 to 3 mm reflective guy cord used on MSR, Big Agnes, Nemo and Decathlon Quechua tents, replacing the sliders that snap in the cold or vanish in the grass. The body is 45 mm long, 12 mm wide and 5 mm thick with two 3.4 mm cord holes and a 3.4 mm friction slot, edges rounded 1 mm so the cord does not fray, and a raised arrow so you thread it the right way in the dark. Print a dozen flat in PETG or nylon at 100 percent infill; glow filament is a nice touch.

Example prompt
Design a tent guy line tensioner 45 mm long, 12 mm wide and 5 mm thick with two 3.4 mm through holes 15 mm apart and a 3.4 mm wide friction slot at one end angled 20 degrees, 1 mm rounded edges and a raised 0.5 mm arrow on top.
Fit notes
Cord diameters differ between tents and a tensioner drilled for 3 mm slips on 2 mm line, so generating the holes for your actual cord makes the difference between a taut fly and a flapping one. Type your cord size into SpeakCAD, preview the tensioner in the browser, adjust the slot bite 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.
