I was impressed by the curling game at the 2022 Beijing Olympics, especially the success of the Japanese "Loco Solare" team, so I made an accessory case in the shape of a curling stone. The diameter is 80 mm.

[design points]
-designed to print as no support as possible.
-the cap is not a screw, but a 1/4 turn type that can be easily locked.

[print conditions]
-printing type: FDM
-printer: Original Prusa i3 MKS
-filament: PETG (cap, handle), PLA(stone)
-support: no (cap, stone), yes (handle)
-brim: no
-raft: doesn't matter
-print with the handle lying on the bed to maintain the strength.
By the way, the stone in the photo changes the color of the filament at 12mm and 22mm from the bottom.

[post printing]
-glue the cap and handle together

[revision]
2022/03/04
-A small protrusion has been added to the stone to make it easier to see where to insert the cap.

2022/03/03
-I made the cap a little thicker.

2022/03/02
-The diameter of the cap has been increased a little to make it closer to the image of an actual curling stone.
-The height of the stone has been increased a little.
-The stone was integrated. (I forgot why it was split.)

2022/02/27
-The handle shape has been changed to make the shape closer to the real stone.
-To give a more cute impression the height has been raised a little.
