RC car shock tower brace

A shock tower brace spans the two upper shock mounts and stops the towers flexing or snapping during hard landings. For a 1/10 scale buggy the brace is about 90 mm long, 8 mm wide and 5 mm thick with 3.2 mm holes at each end spaced to match the tower holes, plus a shallow arch in the middle to clear the body. PETG or carbon-filled nylon give the impact resistance PLA lacks, and a 1 mm fillet on every edge helps distribute stress. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.
Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer? We print this part and ship it to your door. See its priceUpdated

Example prompt

Create a shock tower brace 90 mm long, 8 mm wide and 5 mm thick with 3.2 mm mounting holes at 82 mm centres, a 6 mm high arch over the central 40 mm, 1 mm fillets on all edges, and countersunk hole tops for M3 screws.

This prompt comes with the ready-made model when you sign in, in case you want the AI to redesign it (3 credits a redesign); changing numbers in the viewer is free.

Fit notes

Every chassis has a different hole spacing, so generating the brace with SpeakCAD means it fits the first time. Provide the distance between mounts and the clearance you need, adjust the thickness in the chat if your car is heavier, and preview in the browser.

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.
