For everybody who has bought Chucha TV's drawing of Thermocamera for Flying Bear Ghost 5 3D printer (https://www.youtube.com/watch?v=SvvChheM32c&ab_channel=ChuchaTV) I've designed additional parts that allows you quickly install and uninstall the top box to get fast and easy access to your filament spool without unscrewing 12 screws each time you need to get that access. It is designed for 4mm acrilyc. For myself I've printed them with black and white ABS+ filament. To install it you'd have printed parts in quantity specified in the file name (e.g. "...x2" or "...x12") and 16 screws M3x14 or M3x16 with 16 nuts M3. Here's the only one part of 9. The full set you can download out from here: https://cults3d.com/en/3d-model/gadget/planks-for-easy-connection-of-chuchatv-boxes-of-thermocamera-for-flying-bear-ghost-5-3d-printer
