The brief

This product was developed as a practical, repeatable accessory for sale on eBay. The goal was simple: create a small two-piece set that lifts the rear of a laptop near the hinge area, improves airflow underneath the machine, and gives the keyboard a slightly more comfortable angle for typing.

Unlike a bulky desk stand or fan-driven cooling pad, this solution stays minimal. Each set includes a left and right riser that can be fitted quickly and removed just as easily. The result is compact, lightweight and straightforward to ship as a small consumer product.

Why this worked well as an FDM product

This is exactly the kind of accessory where FDM printing in PLA makes sense. The part needs to look clean, feel solid and stay affordable enough to work as a real product rather than just a one-off experiment.

PLA offered the best balance for the job. It prints neatly, keeps the visible finish tidy, supports a wide choice of colours and keeps production cost under control. In practice, it also suits the application well because the risers sit on the outside of the laptop body rather than inside a high-temperature enclosure.

More engineering-focused materials such as ABS or ASA would have pushed the manufacturing cost up unnecessarily, while PETG would not have delivered the same clean visual finish for this type of small consumer-facing item.

Design, size range and production choices

The design itself is based on a practical existing concept, but it was refined and adapted into a more saleable product format. That included cosmetic cleanup and the development of two size bands rather than just a single generic version.

The small size suits laptops roughly up to 20 mm thick, while the large size is intended for thicker machines in the 30 to 35 mm range. That makes the product useful across both slim everyday laptops and larger gaming-style devices.

The parts are printed on Bambu Lab machines with 100% infill for strength and repeatability. Post-processing is minimal: only light cleanup is needed where required, with no sanding, painting, gluing or assembly.

Colour options and product presentation

The product is available in multiple colours, including black, red, blue, green and other bright options. That matters because this is not purely an engineering part — it is also a retail product, so visual presentation still plays a role.

Large black laptop riser feet shown from above. — The larger size extends the same idea to chunkier laptops where extra clearance at the rear edge matters more.

Result

This project is a strong example of how 3D printing can support small repeat product lines, not just one-off client jobs. It solves a real everyday problem, works across more than one laptop size, and remains inexpensive enough to sell as a practical accessory.

From a portfolio perspective, it also demonstrates a useful commercial pattern: take a simple concept, refine it into a product with clear size options, clean production workflow and low-friction fulfilment, then package it as a repeatable listing rather than a custom-only service.
