500W Spindle Motor - Cooling Fan

prusaprinters

<p>This is an upgrade for the standard cooling fan included with the 500W Spindle commonly used on small DIY CNC milling machines. &nbsp;It prints easily and needs no supports. &nbsp;There is an open and a closed version, depending on personal preferences. &nbsp;</p><p>The hole is a tight fit and you may need to ream the hole with an 8mm drill. &nbsp;I printed it in PETG, as the spindle does get warm in use and have had no isuues with over a hundred hours of use. &nbsp;You'll need a new C-clip, as getting the old one off without damaging it will take more luck than judgement.</p>
