Temperature Controlled LACK Enclosure with Motion Sensor LED LightsDOWNLOAD Version 2.1 (2020-02-25) ZIP ~10MBDetailed HELP with images on how to assemble enclosure (external link)...INTROBelow you will find parts and tools, which will help you to assemble enclosure. If you noticed mistakes, have questions or suggestions, please write to info@jocys.com • Project page: Jocys.com/EnclosureMaximum temperature inside enclosure depends on temperature of the room and heated 3D printer bed. Stable higher temperature inside enclosure reduces warping and detaching of bigger parts from the plate. Control precision is 1°C. HOW IT WORKS: If temperature rises +1°C above set limit (for example, set limit is +40°C and temperature rises to +41°C), two “MH1210A” controllers start fans (ventilation) and drop temperature to +40°C. Tested temperature limit inside enclosure +46°C (room +28°C, heated bed +85°C, extruder +240°C). In order to achieve even higher temperatures inside enclosure, insulation must be added to windows and door. All enclosure parts (cut perspex sheets, ~2kg PETG filament (20% infill), bottle of Windex, smoke alarm, cables, controllers, etc.) cost me about €260 (tools are not included).E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems. Therefore, for PETG filament, I set both enclosure fans to keep 35°C inside enclosure.Parts were printed from PETG with Prusa3D i3 MK3 Printer.If your printer is not precise enough, printed parts may not fit into each other. To test, if your printer is precise enough, you can print and try to fit into each other these two parts from “Table_3_Leg_Top_Ends.STL” file. Spaces between some parts are 0.1mm only.1mm spaces between perspex sheets and table are for even ventilation.2 temperature controller-fan sets are for safety, in case one set malfunctions.If you made your own updates or (file) changes, related to this project, please send me a link.

I printed BIG parts in already partly assembled Temperature Controlled Enclosure. Temperature inside enclosure was 35°C with these bed settings. E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak.
