Low-Key was a two-person venture between Devansh and me: we designed, 3D-printed and sold a line of 14 keychains and collectibles at Felicity, IIIT Hyderabad’s college fest, all in one day of sales. Our cheap impulse items (₹29–₹59) sold out, while the ₹75–₹99 dinosaurs and snakes mostly didn’t, which taught us how to price and stock for next time.

Fest stalls usually sell food or generic merch. We had a 3D printer and design skills, and we bet that students would pay for small, funny, personal objects if the price felt like an impulse buy.

That bet set three rules for the product: keep the entry price low enough to buy without thinking (from ₹19), include pieces that are simply funny, like the joke Hand, and offer each design in up to eight colours so it felt like the buyer’s own.

The name is a pun students get at a glance: ‘low-key’, everyday campus slang, written as लो-KEY. लो (lo) is Hindi for ‘here, take it’, and KEY is what we were selling. The logo is itself shaped like a keychain tag, ring hole and all, so the brand and the product look like the same thing.

We built a 14-design catalogue in price tiers, from impulse buys to one showpiece, and also cleared Devansh’s older Minecraft and Pokémon prints at ₹99 each.

Each design came in up to eight filament colours: olive green, baby pink, lavender, white, yellow, light blue, black and red. We set a target of 311 units, worth ₹19,628 at list price, and tracked stock against it for every design and colour. When pink and purple ran short, we scheduled targeted print runs to fill the gaps.

Production was split between the college workshop and Kaushal’s printer, batched by colour so we changed filament less often. One batch of about 65 pieces used roughly 700 g of filament.

We designed the logo and the poster in-house before the fest. The poster answers every question a passing student has in one look: what (cool keychains, cool prices), when and where (11 AM–6 PM, 13 February, at the Football Ground) and the hook, starting at ₹19.

We laid the stall out to minimise movement on both sides of the table. Products sat in open boxes along a single table, grouped by design and labelled with their prices, so a buyer could see, compare and pick from one spot. The poster hung from the front of the table to pull people in, and payment ran through a QR code at the stall, so an order went from picked to paid without anyone walking around.

Every order was logged in a shared sheet by customer name, amount and product number. That log is the dataset behind the numbers on this page.

Impulse pricing drove volume. The most-bought items were all ₹29–₹59, and the most common order was a two-item ₹69 combo of Low-Dey and Hand. It came up so often that it was effectively a bundle we never designed on purpose.

Bundles raised order value. The median order was ₹69 but the average was ₹95, pulled up by a few large orders (₹739, ₹454, ₹385, ₹367), mostly people buying several Hearts and Roses as gifts. The largest single order was 11 items.

The stall kept selling after it closed. We took custom requests for specific colours and characters over WhatsApp, with UPI payment, then printed and delivered them after the fest, letting each buyer know with a branded “Your Order is Ready!” message. Pre-orders added ₹3,398 on top of the stall’s takings, and every one of them was personalised.

The collectibles were overproduced. They were the longest prints and the highest prices, so they tied up the most printer time and money for the least return. Overall, about 96 of roughly 298 units were left over, a ~68% sell-through.

Nostalgia sold well: 11 of the 14 Minecraft pieces from Devansh’s old prints sold at ₹99 each, a better sell-through than our own ₹75 dinosaurs.

We broke even at about ₹4,750 in sales, less than half of what the stall took in its one day. Everything after that, including every pre-order, was profit.
