Lifted Polydryer Spool Roller Upgraded

I remixed the original model, gave it a test run, and realized the plastic nubs were just too weak when one broke on me. I then revised the design one more time to take advantage of the nice steel tubes Polymaker provided us with for a stronger sag & warp resistant axle. The point of this remix is to get the spool to sit up just a little higher to make sure there's clearance for the desiccant boxes shown in the bottom of my dryer. The extra lift also allows some air to flow under the roller and through / over the desiccant box. In order to take advantage of this print you will need the bearings and the steel tube from your Polymaker Dryboxes. I suggest printing in ABS or ASA or some other high temp filament as the back roller sits right in line with all the heat during drying.I'll suggest Bambu ASA in their green that is more teal looking to me, but I personally printed these in Polymaker Teal ABS and used the Bambu ABS profile.
