I remembered having this type of toy in a kids magic set when i was smaller. So instead of buying it again, i tried designing it myself. Hope you enjoy it as much as i do and let me know what things to improve!

NOTE : The pin and hole positions arent symmetrical. If the sliding piece doesnt go fully inside the outer shell and you encounter a firm stop or increasing resistance (because the pin tip is chamfered it could still go in the hole even if its not in the right orientation) you have it the wrong way.

Easy asembly! No glue/ screws

STEP 1

Print out all the parts

STEP 2

Insert the small plate with two circles in the inner shell as shown in the GIF

STEP 3

Place the lid on the shell

STEP 4

Press the lid edges with firm pressure until it snaps in

STEP 5

Insert the slider in the outer shell and enjoy

By changing which end of the slider goes in first you switch the visible chamber. So here i pushed the slider in, took it out, rotated it to the other side, put the coin inside and then when the slider gets pushed in again it switches to the other empty chamber making it look like the coin has vanished.
