The Original has the issue that you had to sand the connections to fit. Also, the connections was to thin so that the constructions start to collapse if the rack was to full.
I changed the tolerances for a better fit, and modified the legs. and create some new snug fit connections.
Assambling:
first stick together the left and the right parts. than put the left and right part together. to fix it, u can use a drop of glue.
The author remixed this model.
