INTRO

Below 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/enclosure

Maximum 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 (cutted perspex sheets, ~2kg PETG filament (20% infill), bottle of Windex, smoke alarm, cables, controllers, etc.) cost me about €260 (tools are not included).

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 will add this link to your work on this page.

PETG FILAMENT

You will need about 2 kg with 20% infill

I would not recommend to print parts from ABS (shrinkage is too big) or PLA (low heat resistance).

I had no problems with these filaments:

MCPP • BasicFil Black PETG 1.75
Amazon • AmazonBasics Black PETG 1.75
3DPrintz • Black PETG 1.75

PRINTING SETTINGS

Printing Settings for 3DPrintz PETG Filament on PrusaSlicer
...for Spring Steel Sheet with Smooth Double-sided PEI

For BIG parts to stick on TEXTURED PEI Powder-coated Spring Steel Sheet sheet, I increased recommended bed temperature from 60-80°C (for AmazonBasic and MCPP BasicFill PETG filaments) to 85°C (First layer) and 90°C (Other layers). I printed BIG parts in already partly assembled Temperature Controlled Enclosure. Temperature inside enclosure was about +45°C with these bed settings.

Prusa3D • PrusaSlicer

Modified settings: PrusaSlicer > Filament Settings > Prusament PETG > Filament

• "Extruder: 220°C".
• "Bed: 80°C".

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Layers and perimeters

• "Ensure vertical shell thickness: disabled" - I had problems with thin 45° hanging angles when it was enabled.
• "Perimeters: 3" - infill pattern is less visible on surface.

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Inflill

• "Fill density: 20%".
• "Fill density: 60%" - for door and windows holding parts.

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Speed

• Reduced printing speeds (10-20-180-400). Slower speeds results in smoother and glossier surfaces without matte areas, reduces printing noise with vibrations... lesser probability for corners of big parts to unstick from heated bed, because of shrinking.
• "Travel: 180" - low speeds (like 20) creates surface blobs after long travel distances.
• "First layer speed: 10" - for better adhesion.

Modified settings: PrusaSlicer > Printer Settings > Original Prusa i3 MK3S > Custom G-code

• I added few lines to G-code to remove filament blob on nozzle right before printing starts and raised intro line to reduce wearing of steel sheet plate surface.

G1 Z50 ; ADDED LINE --- Z Up to clean filament blob from nozzle
G1 Z-50 ; ADDED LINE --- Z Down
G1 Z0.50 ; ADDED LINE --- Z Up for less intro line adhesion to prevent surface of steel sheet plate from wearing

STL FILES

For better quality and safety... I printed majority of parts separately.

To split group and to remove some parts:
1. Open “*.STL” file in PrusaSlicer Edition.
2. Click on [ Split to objects ] button.
3. Select parts one by one, which you don't want to print.
4. Press [ Del ] key on keyboard.

	You can edit STL files with free and open source 3D creation suite Blender.
	Import “*.STL” file: 1. Blender 2.8 > File > Import > Stl (.stl). If imported STL object is not visible: 1. Select imported object in “Scene Collection” list (top-right panel). 2. In “Object Mode“ (top-left drop-down) > Object > Set Origin > Geometry to Origin.
