 I have a Prusa i3 mk2.5 in storage. I used to use it in my shed I used not to worry about it's harmful emissions: I just didn't share the space with it. I had, however, added an enclosure, and was planning to add a HEPA filter too it. Once it's in an enclosure, it's massive. Even if I had added the filter, there's no where to put it. I'd like a small printer that has an enclosure or is easy to enclose. I figure I could get by with 150x150x150 build area: I was rarely patient enough to wait for my i3 to print bigger models. 200x200x200 would probably actually replace my current printer, so that would be a bonus. Not many printers have HEPA filters, which is really a shame. It seems just to be the result of a misconception about HEPA filters, and about filtration in general. Read this . E.g. I was looking at a used Lulzbot mini, and there are ready made enclosure s for it, however . In this particular case, it's no big deal: opportunities to buy a Lulzbot min

 I'm sure I've mentioned JSK-koubou  before. There's a tool he uses in lots of videos: It's a magnetic drill guide . I've never seen him use the magnetic function: he just clamps it to things to drill accurately, and it's superbly versatile. I don't have access to a shop of any sort at the moment, but I do have hand tools. It might be possible to make something like this Drill Press . maybe I can mash up these two things: I want to use a cordless drill without a collar, so I bought this chuck and spindle from Banggood  like the one used in the drill guide. I also bought some draw runners . These are a bit stiff, but they have no play at all, so it must be possible to produce something very precise and robust with them. I'm really surprised. Everything else will be made of 12mm plywood. Most of the assembly techniques will come from the drill press, including the double sided tape, etc. I want the drill guide because it's something I can conveniently
