I just finished putting together my new leo rack I made from Ikea. The only thing is I was short 1 shelf so I have to go back and pick up one more. It holds 10 cb30 iris tubs and 15 13.5 qt iris tubs. This was my 1st atempt at building a rack so figured I build it for my leo's and see how it would come out. The frame(90$) and shelves(2 for 15$) are from ikea. I basically just put frame together as instructed by directions and then screwed the shelves right into frame to fit the size of the boxes I was using. Whole unit is heated by flex watt 11 inch for the cb30's and 4 inch for the 13.5 qt. Here are a few pics...
For the heat tape the bottom 5 levels I used the 11 inch heat tape and wired them all individually so I don't need to run every level if it is not needed. I secured the heat tape down and covered it with 6 in flashing to protect it from tubs sliding over it. Then just secured flashing down with foil tape. The top 5 levels I used the 4 in heat tape but wired all the levels together on one cord.
The final outcome minus the one shelf....
In the end it came out pretty good. Had a bunch of extra space but knew I would, could of cut all the shelves and frame to shrink it down but for this one was just trying a basic idea. The total for the whole thing not counting the thermostate was $300 with all the tubs and heat tape. I have my herpstate hooked up to it and so far everything is working just as it should. Let me know what you think and if you have any ideas on how to improve the design.
