CR-10 Control Box feet
thingiverse
These feet will prop up your control box 20mm, allowing the fan to breathe better. Saw the opportunity to add a slot for a SD card extension ribbon cable. If you don't to go that route, then just print 2 or 3 of the normal ones. Use 3x10mm and 3x4mm machine screws to mount.
