1Print the three 3D parts
Print these in decent quality as the rotation of the Kaleidoscope will work much better with high quality prints. I printed these slow, taking ~12 hours to print all 3 parts in black PLA
2Tape mirrors together in a triangle configuration
I bought 2" x 6" glass mirrors off of Amazon for $15 for a 10pack.
3Put the rotating turret on
Look for the triangles to align this and slide it on. It should rotate freely.
4Assemble the disk!
I used silver dollar coin holders as the specimen holder. These are ~$2 each, can be bought online if you search for Y-65 Capsule 65mm. Here is one source.
Assemble the disk with the 3D printed spacer - this allows for more room inside and also stops the disk from closing completely, which is great for protecting coins but I found it super hard to open it up again.
You may want to cut some circular tissue paper as I've done here to line the disk, as it makes a nice background for the items in the disk.
5Put it together and kaleidoscope!
