This is a what I call the QuickDrop :-) I made it in two different heights. One is 35mm high for a level on 3 standard tiles, the other 40mm for a level on top of 3 and a half tile.

Here's a video with most of the elements in my library. And... a preview of the lapse timer I am about to release. The lapse timer has custom electronics that I will be making in small batches. If you are interested in the lapse timer drop me a message. If there's enough interest, I could consider ordering larger batches of circuit boards and components.
