Remix from https://www.thingiverse.com/thing:1600793 as planter. Thanks to 3DWP for the great scan.

There are two versions - with and without drainage.

It is 200 x 88 x 155mm (fit rotated on a 200x200 printer bed) If you scale it maybe use the version without drainage and add your own one. It should be uploadable to tinkercad to customize it.

You will need support on the base layers - so what.

I did not print it yet - I just remixed it for fun.

Additional I add a scaled version with 100 x 44 x 78mm with a drainage - maybe for an cactus. Without a drainage you can scale by yourself from the huge one.

You need the left one? Mirror it in your slicer.
