The original design is great (tried several and this suits me best) but my printer was suffering from the notches - so I joined them.
Added version 2.0 enlarging the cap diameter from original 33mm to 37mm and adding a slant to block out maximum light while still supporting OEM AeroGarden holders and transparent domes (the photo is of the original 33mm mod)
