Spool Drying Covers

I needed a cover for the filament drying on the print plate and generated one for one spool which could be printed on every printer which has >=250mm x/y bed and another one which can hold up to two rolls but I can print only on my K2Plus.I print it in PETG and can set bed temp to 75 without problems to dry PETG rolls. PLA rolls (mainly I need to dry extrudr Greentec Pro or some wood and CF filaments) I dry between 50 and 55° bed temperature. Other filaments may require higher temperatures and I may print one cover also in ASA to get to the 100° the bed of my K2 can manage.
