Add a little nintendo fun to your egg hunt this year by incorporating Yoshi's eggs!  Super easy to print and highly customizable; the possibilities are limited only by your creativity (and filament colors!).  Bottom pulls out to reveal a storage compartment large enough for small candy or trinkets.

Printing:  I printed the top (main) portion using a brim and that seemed to work well, but may not be necessary for all printers.  No supports are necessary.

Assembly (Bottom):  The tolerance is pretty tight for the bottom to slide in (especially if you use a brim). Depending on your printer you may need to slowly work it in then slide in and out several times to smooth any rough edges.  After that it should be easy to insert and remove as needed.  

Assembly (Spots):  The spots are all uniquely shaped and will only fit their corresponding holes.  The tolerance is bigger for these so a dab of glue is required to permanently seat.

Have fun!
