Remix: Spongebob's House Planter

Thanks to @reno77 for the great, original design.

Update 2019-04-18:
added a version without drain hole, as requested by sibaar.

To customize it for my needs, I:

scaled it up to 75mm tall
hollowed it out completely, not just halfway down, to allow for more soil and root space, and to use less filament
reduced the size of the bottom drain hole to around 8mm
