DIY sort of, but last night I ordered a nail polish display stand from Amazon (£17.99) for my juices, it arrived today and after stacking it up with my bottles I had an idea, how can I make this a tank stand also...... It's not quite DIY more a modification and re-purposing...... After drilling a few holes BINGO Rather pleased with it and hold my main stuff nicely. Basically the bottom tray needs raising to allow clearance for the 510 connectors, raise the tray up about 5mm then drill 2 new holes above the existing one on each side (4 holes) and that's all there is to it for the height. Next I spaced and drilled 7 equally spaced holes into the base of the tray 7mm Diameter, cleaned it up and fitted it together - Job done! You could skip step 1 and just drill any other tray but I think the tanks look better at the bottom. Pics of modifications included. Let me know if you need any more information.
