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
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
What it's for A Christmas tree lantern with perforated walls that hides a 38 mm battery LED light. A removable twist-lock tray inside the base holds the light, so it stays in the tree when the tree is carried or moved. Dimensions Base diameter: 90 mm, open underneath Total height: about 140 mm including the star Wall thickness: 1.6 mm Light ring: 39.4 mm inside diameter, 6 mm tall Tray: 66 mm disc with three locking lugs Assembly Line the tray lugs up with the gaps between the three tabs inside the wall. Push the tray up past the tabs, turn it about 60°, and lower it onto the tabs. Place the light in the ring. Remix ideas Make the ring taller for a deeper hold. Add a thumb notch to the tray for easier twisting. Change the hole pattern for different light dots.
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.
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.
