I kept my silicone trays to hold desiccant but put on the full sides. The back side I bolted directly to the end pieces but to make removal of the trays easier I just stuck 4 medium sized finishing nails into the bolt holes. In order to make them a little easier to remove I printed some small thumb tack ends to fit over the nails.

I had some really damp filament so I boosted the temps up to close to 60. Not a problem unless the filament touches or gets close to the aluminum tubing. At 60 its hot enough to soften and warp a single strand that is close to the heat source. The aluminum acts as a conductor so it can heat up quite a bit. If I need to heat to that high a temp I ensure my filament is rolled onto the spool and does not hang close to the aluminum. If I am going to dry while I print I make sure I keep the temps down below 40.
I also have never got around to drilling and fastening the aluminum tubing
