Axis and Tower Markers for 3D Printers

playing with a printer a lot? specifically a delta with 2020 extrusion towers? ever get mixed up which tower is which? print these off and add them to your printer, you can use them to mark you axis' towers so you never forget again

update 1:
print with the base down and support on (pillars worked well for me, other directions will result in lots of small support to remove)
there are 2 group stl files included, 1 has x,y,z and H, the other just xyz
they are oriented in the best direction
