Prusa SL1S enclosure

<h3>2022-01-10 update</h3> It works! I've been using the sl1s now for a couple of days and the odors go out. If I'd do this again I would change the configuration so that (assuming CW1S on left side, SL1S on right side of the table) - Left and back side plastic panes would be static i.e. mounted to the table - Front, top and right side panes would be bundled together as a removable part This would allow unhindered access to SL1S when removing the print<h3> </h3><h3> </h3><h3>Pre-word</h3>There is probably more sensible, fast and user friendly way to do the enclosure for the SL1S printer. My approach here is based on several factors: • The lead time for SL1S is longish so I had time to think and tinker the enclosure • I already had some of the hardware available ○ Tables ○ 2.5 mm metal rod ○ Cutting board ○ Screws and bolts and nuts ○ Magnets • I found some almost-made-to-fit hardware in local stores on-the-shelf ○ Fan ○ Wheels ○ Plastic planes ○ Telescopic drawer supportsAs I didn't have the printer at the time of build I also made several assumptions • The enclosure doesn't have to be air tight as there is a fan pushing the airflow out (of a window) • SL1S and CW1S total weight is enough that the light alignment parts are adequate to keep 2 tables mounted on top of each other • There might be situation where opening only the front plane is enough.Printing parts • 20 % infill • Adaptive cubic infill • Supports when needed • 70% infill for some of the smaller parts All connectors are designed with zero tolerance, depending your printer and slicer there might be a need to sand them a bit in order to make parts fitPlease let me know if some files are missing or any instructions are unclear.<h3>Lack</h3>Table tower • 2 x Ikea Lack table set <a href="https://www.ikea.com/fi/fi/p/lack-sarjapoeytae-2-osaa-harmaa-60349262/">https://www.ikea.com/fi/fi/p/lack-sarjapoeytae-2-osaa-harmaa-60349262/</a> • 1 x <a href="https://www.biltema.fi/rakentaminen/helat-ja-helatarvikkeet/kalustepyorat/jarrullinen-kaksoispyora-4-kpl-2000041371">https://www.biltema.fi/rakentaminen/helat-ja-helatarvikkeet/kalustepyorat/jarrullinen-kaksoispyora-4-kpl-2000041371</a> • Lack leg alignment.stl (x4)Using taller legs, the work plane height with the wheels is 97 cm, switching one or 2 set of legs to shorter ones provides work plane height of 87 or 77 cm • Print 4 x part • Put tables on top of each other, align and and screw printed parts on to the top of lower table. • Screw wheels to the lower table. Work plane • 1 x Ikea Sysselsätta cutting board <a href="https://www.ikea.com/fi/fi/p/sysselsaetta-leikkuulauta-30359016/">https://www.ikea.com/fi/fi/p/sysselsaetta-leikkuulauta-30359016/</a> • 1 x Telescopic drawer support <a href="https://www.biltema.fi/rakentaminen/saranat/erikoissaranat/teleskooppikannattimet-2-kpl-2000018627">https://www.biltema.fi/rakentaminen/saranat/erikoissaranat/teleskooppikannattimet-2-kpl-2000018627</a> • Lack cutting board ends 2.stl • Lack cutting board mount x4.stl• Don't overtighten the screws, both the cutting board and the Lack table are soft materials, especially the table which is in practice made of honeycomb cardboard • Attach the drawer supports to printed parts with screws that come with the HW • Align to front, screw and glue to the bottom of the upper table.
