Easy print and very entertaining.

Great utilitarian print! I used a combination of 16mm and 19mm shelves using 4 sets of the long RACKA. I highly recommend using a pipe cutter (copper tubing cutter) as it gives you one of the cleanest and most straight cuts. When you put a full load on the 16mm (10 full spools) the sagging is obvious and I will buy two more RACKAs to make all the shelves 19mm. Also not sure if it is by design, but the front pipes do not click much. Not that this has been a problem, but I thought I should mention it. I put some electrical tape on the RACKA's ends anyway to protect BILLY :)
