Original Prusa MINI Enclosure - some technical details
OK, finally had time to unpack the Original Prusa MINI Enclosure (without any addons) and assembled it partially.Unfortunately I cannot upload images to forum, maybe add some later on in the following posts.Below are some notes, notice that I want to use it a bit differently than the originally intended - that is I want to use left side as doors and put a concrete slab in it.
- Material: steel, doors use 2 magnets 20x6x2 mm, powder coated and it gives that similiar look to the printed parts.
- Dimensions: 430 mm (w) × 470 mm (h) × 500 mm (d) with legs, but notice that power supply is on the outside so this takes additional space
- You can put Prusa Mini printer rotated 90 degrees and it will fit in but you may have to use angled power connector to the heat bed (otherwise it will hit the panels). Yet you may need to put panels on the outside in such configuration:
- instead of three damping pegs you can put a damping cloth + paver or concrete slab on the bottom and place a printer on it and you should still have about 2 cm of free space between Z motor and the ceiling. Notice that the whole setup gets really heavy and I am not sure if the handles in side panels would be good enough to transport it. I guess it would be better to add additional handles for transport.
- Holes for USB in the front has size of 13x25 mm, again mounted in such way that I just can image people breaking their pendrives by accident 😉
- Holes for Humidity/Temperature sensor in the front/back size are 60mm apart, but the holes on the sides are ~62 mm apart, so you cannot mount humidity sensor on the side (a bit surprising I'd say) unless you redesign 3d printed mounting bracket:
- Side panel - mounting hinges will need some redesign, also cutting the panel is inevitable, more on that in next posts
Other notes:
- the edges are not that sharp as I would expect - I guess they were slightly smoothed, so they are safe to use
- the overall sturdiness of the enclosure is good, you can easily stack 3 on each other
- enclosure is not air tight - (you can see it on the photos above) there is a lot of holes in the enclosure due to the fact that you can attach cables with zip ties, also on the corners between the metal parts there are gaps, I guess less than 0.5mm - you may need to cover them with duct tape or something like that or use fan + pipe to attach on the back to generate negative pressure (and it wold also require a filtering loop or route outside etc). Also you want to tape side panels and holes on the bottom.- air filter is inside so it just sucks in air and filters it over HEPA filter, so the idea is similar to NeverMore but with HEPA instead of active carbon pellets.
