60 cm Cubic Enclosure with Easy Detaching Panels

thingiverse

A 60 cm cubic enclosure for 3D printers. It is designed to allow access from all directions (for CoreXY 3D printers). Panels are only "hooked/hanged" onto the frames for easy detaching. Thermally, the sealing should be good enough (my poorly designed PLA belt tighteners on the hotend carriage were once softened with a 60 °C bed temperature inside the enclosure). Acoustically, the sealing is not good enough to meet my expectation. Probably because the plastic sheets bend easily and cannot press firmly against the window seals. I also didn't seal the printed corners. Fusion 360 design file attached. #Non-printed parts Besides the printed parts, the design also needs: * 12×12×1.6 mm metal angle extrusions for frames, cut to 570 mm long, 12 pieces; * 3-mm- or 5-mm-thick (acrylic) plastic sheets for panels, cut to 60 cm × 60 cm, 5 pieces (if the enclosure will be placed against wall, then only 4 plastic sheets needed); and * M3 screws that are between 10 to 20 mm long (e.g. 15 mm) to fasten the frames, 24 pieces (and nuts too; maybe washers as well). I also attached window seals (6-mm thick) for better sealing. Each facet needs about 4 × 60 = 240 cm. So totally about 12 metres for 5 facets. The gap between the angle frames and the panels is about 5 mm. The gap between the printed corners and the panels is about 3 mm. #Printed parts Parts to be printed: * *Corner* × 8; * *Clamp* × 24; * *Hook*, 4 for each panel, use *Hook 3mm* and *Hook 5mm* according to the thickness of plastic sheets. **All parts are designed to be printed with 0.4 mm layer height, without support.** #Fastening the angle frames The clamps were not planned with enough clearance for errors. However, just tighten them, and the angle frames will be held firmly together anyway. #Attaching the hooks I only used double tapes (several layers) to attach the *hooks* onto the panels. I might super glue them later, as this is irreversible. #Updates It appears that 60cm height may leave too little clearance for CoreXY printers. The filament gets softened in the PTFE feeding tube and eventually clogged. Hence, I think this enclosure should be (X mm) taller: - Replace 4 of the 570mm-long angle extrusions with (570 + X)mm. - Replace 4 (or 3, if placed against wall) of the 600×600mm plastic sheet with (600 + X)×600mm ones. X should be something like 150mm (15cm).
