HAND-CRANKED FLIP WINDOW

The Christmas Shop

Two canal houses on a frozen canal street. Turn the street organ's crank and twenty Christmas pictures flip in the shop window, one click at a time, while the organ's drummer and bell-ringer bob up and down in turn.

You need
The ten plates in christmas_shop_sliced.3mf (about 18 h, 461 g of PLA). Dark green, white, yellow and red PLA, a latte brown for the wood and a pale blue for the ice. Three M2 pan-head screws: one M2×16, two M2×14 (or 1.75 mm filament).
Good to know
Everything else presses, slides or sits in a pocket. The street is 200 × 136 mm; the set stands about 145 mm tall. Print christmas_shop_fit_test.3mf first: the crank is keyed and goes into the axle one way only.

Assemble

  1. 1Load the spool

    Step 1: Load the spool

    Set spool A disc-down on the loading stand's pin (plate 4). Drop flap N into the slot just right of number N, the top half of picture N facing the number. Press spool B down the tube, lip up, until it stops on the tube's end. Its funnelled holes catch all 20 tabs. Lift the loaded spool off the stand.

  2. 2Spool into the chassis

    Step 2: Spool into the chassis

    Tilt the loaded spool into the chassis: spool B's tube over the stub on the far wall, spool A at the divider's round hole.

  3. 3Axle and ratchet

    Step 3: Axle and ratchet

    Push the keyed axle into the pawl bracket, turning it until the teeth slip past the pawl. Feed its D-shaped tip through the divider into spool A and press the bracket's two pegs into the divider's two small holes. Turn the axle by hand: it clicks once per picture going forward and refuses to turn back.

  4. 4Into the shop

    Step 4: Into the shop

    Slide the chassis into the shop from the back until it clicks over the ridge on the floor.

  5. 5The snowy roofs

    Step 5: The snowy roofs

    Set each roof on the box behind its gable, its skirt down the box's side and its front against the back of the face. Nothing pegs in: they lift off again.

  6. 6Awning, hoist and lantern

    Step 6: Awning, hoist and lantern

    Slide the awning's tongue into the slot over the window. Push the hoist beam into the hole at the top of the bell gable and the lantern bracket into the one by the door; hang the present and the lantern on their hooks.

  7. 7Onto the street

    Step 7: Onto the street

    Lower the shop into its pocket on the canal street, its face along the red-brick cobbles. Leave the four small pockets on the crank side clear: they're for the organ's legs.

  8. 8Figures on the organ's lid

    Step 8: Figures on the organ's lid

    Hold the lid upside down. Push an M2×14 up through each hole and screw the drummer onto the front one, the bell-ringer onto the back one, until each head sits snug under the lid; back each off a quarter turn so it slides. No screws? Push a 15.5 mm piece of 1.75 mm filament 5 mm into each figure's base instead.

  9. 9The organ's cam and rockers

    Step 9: The organ's cam and rockers

    Drop the cam into the case from its open back, its keyed bore toward the shop. Put the two rockers in over it, rocker a (its nose to the front) toward the shop. Drive the M2×16 in from the organ's outer side, through both rockers and into the inner boss (or push in a 19.5 mm piece of filament until it's flush).

  10. 10Organ, crank and lid

    Step 10: Organ, crank and lid

    Stand the organ against the shop's crank side, its four legs in their pockets. Push the crank's peg through the organ and the cam into the axle: it only goes in one way, the groove on the rib, so turn it until it drops in. Put the lid on, figures up: the screw heads land on the rockers. Turn the crank: a picture flips at every click.

  11. 11The canal and the street

    Step 11: The canal and the street

    Lay the ice in the canal and set the bridge across it. Add the skaters, bollards, postbox, tree and snowman in their pockets on the street.
