House Air Filter Retaining Clips

prusaprinters

<p>I swapped to a generic/cheap filter for the air return but the friction fit of the filter was a little loose in the opening. When the furnace stopped circulating air, the filter would fall onto the metal grate below and it was loud enough to bother the family.</p><p>After a couple weeks of noticing this, I figured cheap clips to hold the filter in place were a good enough stop gap.</p><p>&nbsp;</p><p>Printed in PETG for flexibility, no supports.</p><p>Note: because of my poor cad, this shows up as 2 parts in the STL file… you should merge the parts in your slicer.</p>
