MeanWell LRS-350 terminal cover with strain relief

A snap-on guard for the exposed screw terminals on a MeanWell LRS-350 series power supply, whose chassis is 215 x 115 x 30 mm with the terminal block at one end. The cover is 50 mm deep, wraps the full 115 mm width and 30 mm height with 2 mm walls, and hooks onto the two chassis screw holes near the terminals with M3 screws. The rear face has three 8 mm cable exits with printed strain relief ribs so mains and DC leads cannot pull on the screws, and slotted vents keep airflow past the terminal end. Print it open-side down without supports. 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

Adjust

Change its numbers in the viewer for free, or ask the AI in the chat: wall thickness, hole size, the thing it clips onto. AI changes use 2 credits per request (1 for a quick edit, 3 for a redesign), paid with a plan from Maker at $7.99 a month.

Print

Download a watertight STL or 3MF free, with your numbers and hand edits, or G-code sliced for your printer at the same price. After an AI change the download is included in every plan (4 credits without one).

Example prompt

Design a snap-on terminal cover for a MeanWell LRS-350 power supply 115 mm wide and 30 mm tall, cover depth 50 mm with 2 mm walls, two M3 mounting holes matching the chassis, three 8 mm cable exits with strain relief ribs on the rear face and 2 mm ventilation slots on top.

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

A cover measured to your exact supply and cable count is safer than a download that leaves gaps. In SpeakCAD you describe the PSU, preview the cover in the browser, adjust for the LRS-150 or LRS-600 or add a fused inlet hole in the chat, and 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.
