Framework 12 Toaster PC: push the lever, the screen pops up like toast

Push the lever and it boots. Press POP and a 7-inch touchscreen jumps out of the bread slot.

This is a 1950s pop-up toaster built around the Framework Laptop 12 mainboard. The board stands upright in the first slot like a slice of bread. The second slot hides a touchscreen with two slices of toast riding on top. Push it back down and it clicks away, and it's just a toaster on your counter again.

"Can it run on a toaster?" Yes. Yes it can.

🍞 How it works

• The lever is the power button. It pivots on one M3 screw. A nub inside presses the board's own power switch, and a spring strip printed into the lever pops it back up. No metal spring.

• POP launches the screen. The screen sits in a carriage that slides in two guide columns. Two ordinary rubber bands pull it up. A springy hook under the top panel holds it down until you press the POP tab.

• The toaster is the cooling system. The Laptop 12 board has its heat fins along one long edge. Stand it upright with the fins on top and the toaster works like a chimney: cool air comes in through the crumb tray and the side vents, the board's own fan pushes it through the fins, and warm air rises straight out of the bread slot. No extra fans.

✨ Features

• One cable for the screen: the Framework board's USB-C ports carry video, touch and power, so one short right-angle USB-C cable runs the whole screen. No driver board, no soldering.

• All 4 USB-C ports reachable: two on each end, in openings sized for Framework expansion cards, so a card plugs straight into the board through the end wall.

• Fits most 7-inch USB-C touch monitors up to 172 x 106 x 15 mm. Designed around the Waveshare 7EP-CAPLCD and the LESOWN P70D-T.

• Crumb tray slides out of the end and doubles as the air intake grille.

• Wi-Fi ready: the Laptop 12 keeps its antennas in the screen, so the back wall has pockets for stick-on laptop antennas and two holes for screw-on SMA antennas.

• Clock battery pocket for the ML1220 coin cell the board needs when it runs outside the laptop.

• The board mounts with its own 5 captive screws. No inserts, no glue.

• Browning dial from IDLE to BURNT. It does nothing. It's a toaster.

• Built from the real CAD: Framework's official mainboard model and Waveshare's screen model. Every part was checked against both for collisions, including the screen's whole trip up and down through the slot.

🖨 Printing

NO SUPPORTS. NO BRIM. NO MULTI-MATERIAL UNIT NEEDED.

Every part fits a 250 x 250 mm bed and the 3MF files already have each part turned the right way up. The shell prints standing up in one piece. The top panel prints upside down on purpose (its latch hangs underneath).

Each part is one color, so on a single-extruder printer you just change spools between plates. Two plates change color by themselves: the badge and the toast fronts have a pause built into the 3MF at the right layer. Swap to orange or dark brown and press resume. With an AMS or MMU, set the second color at that layer instead.

Settings: PLA, 0.2 mm layers, 3 walls, 15% infill. The lever is best in PETG (it has a spring in it).

🛠 Assembly

About 45 minutes once everything is printed. The 16-page illustrated assembly guide (PDF in the files) has a numbered parts map, the screws drawn at actual size, and one step per page with pictures, labels and a quick check at the end of each step.

1. Feet and crumb tray into the base.

2. Board onto the carrier with its own captive screws. Coin cell into the carrier's pocket.

3. Carrier into the end slots of the base, guide columns into the back sockets.

4. Screen carriage: arm pegs into the holder, arms into the columns, M3 x 25 band pins across the column tops, rubber bands under the arms and over the pins.

5. Lever into the shell on an M3 x 25 axle, knob on.

6. Shell straight down over everything, 4 x M3 x 10 from underneath.

7. Dial and badge.

8. Antennas, the monitor and the right-angle USB-C cable.

9. Toast fronts onto the backs, toast on top of the screen.

10. Top panel on. Push the screen down until the latch clicks.

11. Power into any end port. Push the lever, press POP.

💡 Tips

• Screen doesn't pop all the way? Add a third rubber band. Slams up? Use thinner bands.

• Lever feels tight? Back its screw out half a turn.

• No picture? Use the top port at either end and a cable that carries video ("full featured" or "DP alt mode").

• Keep the bread slot and crumb tray clear. That's the cooling path.
