Range Hood Filter Retaining Spring

thingiverse

This filter spring has been custom designed for a Robinhood Grange range hood. The model number (visible once the filters are removed) is RG6BL. This filter spring may also work for other brands that use a similar design. The original clear plastic filter springs have become brittle and broken. The service manual indicates these are made of polycarbonate. While I have polycarbonate filament, I opted to use PETG as the originals have failed. The service manual can be found here: https://www.manualslib.com/manual/992335/Robinhood-Rg6wh.html According to the service manual, the original part number is 101221 and can be purchased here (for reference): https://genuineapplianceparts.com.au/spring-filter.html The new PETG 3D printed parts work perfectly so far. I will update this if I have any issues with them. Simplify 3D estimates the cost to be 14 cents each. Even if I have to reprint them once a year (unlikely), it will work out to be much cheaper than the $29.55 (incl. shipping) it would cost me to purchase replacements which are likely to fail as the original parts have. Printed on a Creality CR-10 using eSun Solid Grey PETG. Print speed: 60mm/s, hot end: 240°C, heated bed: 60°C, 0.2mm layer height, 0.4mm nozzle. A six perimeter outline brim was used to prime the nozzle and help adhere the part to the heated bed while printing.
