This is for 3D printer usabilities test. It works for me.
You can get one from AliExpress, search "Lazy Snack Dish". It's cheaper.
Before print, make sure maximum effective print area is 200 mm. Especially those Tarantula with Radial Fang + BLTouch or SN04, they don't get that size of print area.
You can scale down, but the grove for phone holder will be scaled as well.
Rotate Z 90 degree.
Support needed for Top part. It's a bit tricky, I printed it without flipped.
