Filament dryer extension for Elechomes Dehydrator

This is an extension for the Elechomes 6 tray food dehydrator from Amazon so that filament spools can be dried without breaking the oem trays. I changed Haprog's Fusion360 file to shrink it to the size of my dehydrator, and parameterized it some to make it easier to adjust. Outer diameter of lower ring: 268mm Outer diameter of upper ring: 263mm Width of rings: 2.2mm I printed it with the existing lower lip height of 10mm, but bumped the upper lip to 16mm. I think I will bump lower_lip_height to 15mm if I print it again but a perfect seal isn't really required. Two 1KG spools fit if they are "regular" width(<68mm), so there shouldn't be any problems with even the widest of spools to at least get 1 in there. The extension meshes well with the Elechomes trays, so they should stack nicely as well. 4 identical pieces slide together to make a hoop, with a lower ring to fit into the base or tray, and a smaller top ring to lock into the lid or tray above it. I might be using it upside-down from its original design, but it works perfectly for the Elechomes with the smaller "ring" on top, which is also the orientation for printing. Print instructions I also recommend printing with a brim, I used 8mm because it made a solid brim between the 4 parts. Using transparent PETG I could see some release from the print bed 1-2mm out from the ends of the part, but it stayed securely in place and was easy to clean up with a deburring tool You should print 2 of the test pieces to make sure your printer/filament settings let them slide together correctly, if not you can increase the "slot_clearance" parameter, but I didn't need to. Haprog's connector design is great, and the slide pin works fine without support, it started in mid-air but came together fine on all 4 for me without needing cleanup.
