Herz-Puzzle-Box "Bis zum Mond und zurück"

This is the version of a Heart Puzzle Box with 0.25 mm gaps and an insert to hold a jewelry item. The version with 0.4 mm gaps could be downloaded at https://cults3d.com/en/3d-model/various/heart-puzzle-box-i-love-you.

This is three-piece box for jewelry and small accessories shaped as a heart. It includes an 11-pcs puzzle that assembles into "To the Moon and Back" text in the frame embossed in the lid part. The insert part separates the box to the upper compartment where you put the jewelry item(s) and the lower compartment to store the puzzle details.

The size of the case allows to put inside various items that you'd like to gift your beloved one, and you can scale it up if necessary. Particularly, you can scale it up 1.5-2x times for printing with 0.3-0.4 mm nozzles. Just keep in mind that original gaps are 0.25 mm, and the more you scale it up, the thicker are the gaps.

Or you can use it as a planter for a cactus! :)

This is the version with 0.25 mm gaps ideal for SLA printers and a bit tight but acceptable for 0,2 mm FDM nozzles if printed 'as is'. Or you can upscale it and use a bigger nozzle.

To find an appropriate scale, print 2-3 connecting puzzle elements and check if they connect not too loose and not too tight. Repeat in a different scale if necessary: enlarge if too tight, or make it smaller if too loose. Once you like the result, this would be your optimal scale.
