LACK Attack #4: Enclose the Lack (aka Quiet The Lack Stack)

Just thinking of doing something like this for my 3d printer and CNC router. But I was thinking... on the enclosure for your printer you are stubbing in the legs from the bottom shelf. and you print a bottom hinge block to use as a riser as well. if you were to instead print another hinge block for the top of the stack and sandwich the leg in between the 2 hinge blocks, you could then make the 2 blocks tall enough to avoid the spliced in leg altogether removing one joint in the leg.

This does of course make the hinge blocks taller and thus take longer to print but the end result may look nicer... I have not actually put my lack table together yet as I am still looking for ideas on how to do this. and I really like your design. but I think for mine I will probably make the upper hinge block and scale them to negate the need for the salvaged legs.

and lastly I am not sure as this picture maybe is not showing it, but does every lack to lack joint over hang the edge so your bumpers go all the way up, from caster to the top lack. and if not that may be a good idea as well as placing a bumper on the top of the entire stack just so it will contact evenly for the entire height of the stack. and sort of add an aesthetic look to the stack assuming you make them in a nice contrasting color. To this end I think I will take your bumper design and place one at every point. including removing the legs and placing them between the legs and the table top so each surface will have a bumper pair. One above and one below every table surface in the stack.

also I was thinking of adding another lack on top to make an airtight box with desiccant tray for filament storage. and place the filament cleaner going up instead of down from the printer level. I have not seriously looked into this yet, but I am thinking if the plexiglass doors had a ferrous metal strip or washers on them and then inside the lack area put a gasket of some sort with very strong neodymium magnets to hold the door tight against the gasket.... not sure about this just the idea in the back of my head. then the desiccant tray would sit on the top of this with a slide out design for easy desiccant rejuvenation. if the desiccant tray was made from some sort of oven safe material you could just slide it out as a cartridge and dry your desiccant in the oven and replace the rejuvenated cartridge when done.
