About · We mail slabs
WE MAIL REAL PLASTIC LETTERS. ON PURPOSE.
Thudletter is a small print shop in Detroit, which is to say, my apartment. We take handwritten letters and print them as plastic slabs. Then we mail them. There is no other product. There is no app. There is no subscription. There is one thing, and we ship it from $29, free shipping included.
01 · Origin
Detroit.
Est. 2026.
Thudletter was started in Detroit in 2026 as the second product out of J&J Dynamic Holdings, LLC. The first was Holdable, a Detroit-based 3D printing operation that runs a wall of Bambu H2C printers around the clock. Thudletter is what happens when you point that print farm at the post office.
People stopped writing letters because the medium got cheap. Email is free. Texts are free. Cards cost $4 and feel like it. Nothing you can lose in a recycling bin in three seconds carries weight.
So we made the letter heavier. Hundreds of grams of PLA, your handwriting raised off the surface, boxed and shipped USPS. The recipient cannot fold it. They cannot toss it without thinking about it. They have to put it somewhere. That is the point.
02 · How it gets made
One farm.
One box.
Every Thudletter prints on a Bambu H2C in Detroit, on the same farm that prints Holdable orders. PLA filament. White slab, black raised letters by default. Other colors when stock allows.
Five to seven days from order to mailbox, depending on size. USPS Ground Advantage from there. United States only at launch.
Every order ships in a fitted presentation box. There is no upgrade tier with a ribbon. The box is the wrap.
03 · Who is behind it
One guy.
One printer wall.
Built by Jack. Detroit. Solo. Prints come off the Bambu H2C farm down the street.
Thudletter is a sister product to holdable.ai. Both are owned and operated by J&J Dynamic Holdings, LLC. Same printers, same packing tape, different product line.
