Extended top corners- Ender 3 Lack Table Enclosure

thingiverse

People don't seem to recognize that these Ikea Lack tables are made of paper and low-density particle board (though bottom surface of the table top is slightly more robust fiberboard). I like fandabrac's 2019 remix for E3 printers a lot because it leaves 2.5 inches of headroom above the printer but out of a surplus of caution I modified the top corners of the fandaabrac remix to extend the leg supports and also offset the mounting holes so now I have additional leg support without risk of multiple screws in same plane within the particle board section of the legs causing a weak zone within the leg. Vertical loads aren't the concern- I'm more concerned with a racking load such as someone leaning on the stacked enclosure. This is just the top corners. Everything else per the original remix post. In retrospect now that the enclosure is finished I think not plugging the 2 duplicate screw holes and using relatively short screws and pre-drilling the holes into the leg would have been good too. Regardless I am happy overall though the entire enclosure is not particularly robust. I see people using concrete blocks under their printers and CNC Kitchen on YouTube makes a compelling case for doing it however I'll be using a large (or maybe 2 stacked) ceramic floor tile because they are thinner and easier to handle and I suspect still have enough mass to do the job.
