I liked Ruslan's box but when using it found I needed some details different. Thus the remix.

• the box for the sensor is longer so it's easier to fit the thing in if you didnt solder the cables but plugged it with duponts
• next to the bottom plate with the half sphere there is now a bottom plate which is just flat
• the bottom has 4 screwholes so you can alternatively screw the bottom
• there is a version of each box variant with holders to screw in at the four corners
• in addition to the vanilla sensor box there are 3 with an extended plate so you can easily put them / screw them on top of something looking straight or down (15° or 30°)
• The foot of the little thing has 2 circular slots to put a magnet in and mount it on a whiteboard or fridge or some other magnetic material. I printed them all with .3mm and 150 mm/sec (nominal) in PLA with no support. Just check their placement in the slicer, unfortunately they mostly default to an absurd position. Place the boxes on the face with the round hole for the sensor facing down. Don't place them on the extended base or you may get stripes on top of the box surface like you can see in one of the pics
