3D Printer Enclosure
Temperature Controlled 3D Printer (Prusa3D i3 MK3) Enclosure STL Files 1.2 (2019-01-14)  

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.

1mm spaces between perspex sheets and table are for even ventilation.

2 temperature controller-fan sets are for safety, in case one set malfunctions.

Tested temperature limit +40°C (didn't want to go higher).
Heat rises from heated printer bed.

Below you will find parts and tools, which will help you to assemble enclosure. If you noticed mistake, have question or suggestion, please write to info@jocys.com

PETG Filament
PETG Filament and Printing Settings

2018-05Prusa3DBlack PETG 1.75€22

2018-05Filament PMBlack PETG 1.75€22

2018-053DPrintzBlack PETG 1.75€27

Prints with 3DPrintz PETG black filament had more pleasant look and even glossiness on all surfaces (top, bottom sides). Parts printed with Prusa3D and Filament-PM filaments had differences in surface glossiness, especially noticeable on top of the parts.

Prusa3D PETG 1.75 and Fillament-PM PETG black filaments are made by the same Plasty Mladeč (Czechia) manufacturer (2018-12-10).

I don't know, who is 3DPrintz PETG filament manufacturer. From design of the spools, this could be NorthBridge (China) sub-brand Kexcelled (China). They claim, that they are "The largest 3D filament manufacturer in East China".

• Extruder and bed temperature settings are for 3DPrintz PETG filament.

(For 3DPrintz) Slic3r Prusa Edition > [ Print Settings ] tab > "Infill" section

• Exception is "Fill density" 60% for glass and door holding parts.

(For 3DPrintz) Slic3r Prusa Edition > [ Print Settings ] tab > "Layers and Perimeters" section

• "Ensure vertical shell thickness: disabled - I had problems with thin 45° hanging angles with this feature enabled.
• "Vertical shells > Perimeters: 3" - infill pattern is not so visible on surface.

• Below are modified "0.20mm FAST MK3" and "Prusa PET" settings, oriented to reduce printing noise (slow printing speed).
• Exception is "Speed for non-print moves > travel: 180" - low speeds, like 20, creates surface blobs after long travel distances.
• You can print (faster) with default-recommended speed settings. Slower speeds gives smoother and glossier surface without matte areas.
