Miniature Pop-Up Toaster, 70x46x45 mm
Created today
Description
A small mechanical toaster printed as separate parts: body, toast carriage, two toast slices and a side lever. Pressing the lever handle down raises the carriage and pops both slices up out of the slots. No springs are used. Lowering the lever pulls the toast back down.
How it works
- The lever pivots on a pin moulded into the right side wall.
- A peg on the lever passes through an arc slot in the wall into a horizontal slot in the carriage side plate. The peg's travel lifts the carriage about 14 mm.
- The ends of the arc slot are the up and down stops. Two floor blocks inside the body act as backup low stops.
- Each toast slice has a tenon that locates in a pocket on its carriage tray.
Specs
- Body: 70 x 46 x 45 mm, open bottom. Print it upside down with the top plate on the bed.
- Overall assembled size: about 76 W x 52 D x 60 H mm with the toast raised.
- Carriage: 1 mm side clearance to the walls. Slice tenon clearance 0.3 mm per side.
- Slots: 27 x 7 mm for slices 25.5 x 5 mm.
- Print settings: PLA, 0.2 mm layers, 3 walls, 10-12% infill. No supports are needed.
- Estimated filament: roughly 35-45 g. This is below the 50-60 g target, so walls can be thickened if more weight is wanted.
Assembly
- Slide the carriage into the body through the open bottom. Slice tenons face up.
- Press the lever hub onto the pivot pin, feeding the peg through the arc slot into the carriage slot.
- Add a dab of glue to the pin head if the snap fit is loose.
- Drop the slices into the slots.

Advent Calendar With 24 Drawers
Advent calendar drawers that stick, fuse, or have nothing to grab. Each of the 24 drawers has a rounded finger grip on the front, a numbered face, and 0.5 mm clearance all round, so it slides out freely after printing in place. Key numbers Footprint: 177.5 × 157.5 mm (fits a 180 × 180 mm bed) Height: about 49.9 mm including grips Layout: 4 columns × 6 rows, printed lying on its back, front facing up Drawer interior: 38.5 × 22 × 42.5 mm Walls: 1.5 mm; grips 8 × 5 mm, 2.5 mm proud Print: white PLA, 0.4 mm nozzle, no supports inside the drawers; the drawer back walls hover 0.4 mm above the frame back, so expect a thin first-layer bridge
整套装配总参考图1800×2400mm Opening Double Door Frame, 1:20
Exploded 1:20 assembly of a hotel automatic double swing door, built for a 90 × 120 mm frame opening (1800 × 2400 mm full size). What it contains Aluminum-style frame: two jambs, head beam and threshold Two glass leaves, 44 × 3 × 118 mm, pulled forward of the frame Top track, motor and two linkage arms lifted above the head Microwave sensor above the track Two infrared photocells moved out to each side Check before printing The 90 × 120 mm opening and 1:20 scale are assumed. Parts are spaced apart for display, not for assembly. Leaf pivot pins and frame sockets are not modelled, so this does not fit a working door mechanism.
Christmas Tree Lantern for LED Tealight
A Christmas tree lantern that sits over a battery LED tealight, so the light stays hidden inside instead of glaring from a bare tealight on the table. The walls are perforated with rings of small round holes that throw dots of light, and the bottom is open so the LED can be placed or swapped without taking anything apart. Key numbers Height: about 135 mm including star Base diameter: 90 mm, open underneath (inner opening about 87 mm) Wall: 1.6 mm, three stacked tiers Perforations: 4.2 mm holes, staggered rings Star: separate colour, peg-mounted into the top tier Printing Print upright, open end down, no supports needed for the cone walls Green for the tree, gold or yellow for the star Use a 0.4 mm nozzle; a lighter or translucent filament glows more

Lamp Bases, Shades and Diffuser Set
A set of mid-century lamp parts that all share one coarse 6 mm-pitch thread, so any shade fits any base. The set has two fluted shades (round and square ribs), a white adjustable diffuser and several bases: tall, short, grooved, two tripods, a flat-leg grooved tripod and a dowel-leg hub. Remix hooks Flat-leg tripod: legs are 16 mm wide slabs (before scaling) with two grooves, 3.2 mm wide, down each outer face. Change the groove count, offset (±4 mm) or width. Leg height and spread: hub height 70 mm and foot radius 70 mm set the splay. Raise both for a taller version. Thread spigot: 52 mm across, 38 mm long. Keep it to stay compatible with the shades. Pairs with: either fluted shade and the diffuser. The 42 mm bore runs straight through for the bulb and cord.
验证质量守恒定律改进实验
A two-ball Newton's cradle that splits into separate pieces for easy printing: base, four posts, two top rails, two axles and two swinging ball pendulums. Both balls hang at rest, touching at the centre. The pendulum hubs ride freely on loose 3 mm axles. Remix hooks Pendulum length: 70 mm arm, 10 mm radius balls. Longer arms give a slower swing. Joint clearance: pegs are 5.6 mm / 4 mm in 6.4 mm / 4.4 mm pockets. Tighten or loosen for your printer. Axle fit: 3 mm axle in a 3.8 mm hub bore and 3.4 mm rail holes. Frame height: the pivot sits 110 mm above the base on a 140 x 50 mm plate. Pairs with: a printed or drawn angle scale or height ruler placed beside the frame, for mass and height experiments. Variants: add more pendulums by adding axle positions along the rails.
