To print these Panel Filer Plates. I printed them with the face down and used support on the side notches. I've Tried them both out of ABS and PLA and both clicked into place perfectly. This got me passed an OSHA inspection in a pinch and beats the $15 each they cost anywhere else. The cover photo shows the PLA version in slot 29 and a original injection molded one in slot 30.
The author marked this model as their own original creation.
