Customizable Queen Excluder
thingiverse
This is a script for customizer to generate queen excluder grids. To make it easier for bees to pass it has slightly rounded bars. I needed this for a mini nuc and thought to challenge myself to make the script suitable for the thingiverse customizer. So use customizer app for this! Size between bars defaults to 4.1mm. Make sure you know what size you need (and that your printer is calibrated right). The excluder works fine for me, but I take no responsibility for your queen.
