Car Blower standalone air filter

prusaprinters

<p>WIP still in design phase, parts should have correct sizing (but dont, in particular the mounting holes on the blower are too far apart), but hasn't been tested for fit</p> <p>Blower (2001 Dodge Ram (et al.) Blower, blower motor resistor not needed):<br/> https://www.amazon.com/Blower-Motor-Fan-5015866AA-Replacement/dp/B07BSSVGBP<br/> ~$35</p> <p>PSU 12V 30A (360W):<br/> https://www.amazon.com/MEAN-WELL-LRS-350-12-Computer-Project/dp/B07VTLJS18<br/> ~$35</p> <p>Controller 30A 12V (360W) PWM controller:<br/> https://www.amazon.com/KeeYees-7-70V-Controller-Switch-Control/dp/B083J3WMND<br/> ~$20</p> <p>(Blower, PSU, controller have been tested together in open) Controller might need to be modified to move switch outside of case (otherwise it will turn on when plugged in)</p> <p>Filter 10x16x1:<br/> https://www.amazon.com/dp/B00CK04APY/<br/> ~$16 per filter for MERV13<br/> ~$12 MERV11<br/> ~$10 MERV8</p> <p>Will need lots of M3 bolts, threaded inserts, tape, 10-12 gauge wire</p> <p>designed to be able to be printed on 220x220x250 printer<br/> (12x24x1 filter add on in the works for 330x330 printers)</p> <p>Frame parts should print with outer wall on bed (small amount of support material for sealing lips)</p> <p>filter frame mounting holes on frame are designed for M3 threaded inserts</p> <p>filter frames should be able to be printed at the same time with 10" section on bed</p> <p>FreeCAD file included, most dimensions can be changed in GeneralDims Spreadsheet</p> <p>Snail casing for Blower traced from Dodge ram HVAC casing<br/> both housings should be able to print without supports (top using right side on bed, bottom printed as orientated) though the bottom has some high angled overhangs near top walls (cura tree supports could help there? (if needed??))</p> <p>hopefully this can help cut down on wildfire smoke / printer particles much better than similarly priced filtration options (~$110 not including wires/bolts/tape)</p> <p>is there any interest in a DIY filter for this? (seen toilet paper used as a at home DIY option, but filter material is also sold online for more "professional" build)</p> <p>TODO:<br/> -Design feet to lift off ground/bind lower two sections<br/> -figure out how to mount the blower and its cover (is mount to housing enough?) weight balance issue?<br/> -better section inter-connections<br/> -inletRing Mounting<br/> -add C13 power socket mounting location<br/> -add blower speed control mounting location<br/> -add attachment for directing output air (want to make bed jet type attachment) (thinking of adding fins to straighten output and double as attachment point)</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Tronxy x5sa Pro</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>Yes</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.8</p></div><strong>Infill:</strong></p> <p>idk</p> <p><strong>Filament:</strong> jill petg/pla bacon <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>use a bigger nozzle/layer height to save time</p></div></p> </p></p> Category: DIY
