Esteps Helper Filament Holder

thingiverse

I always find it very difficult to keep the filament perfectly straight when measuring my esteps, so i designed a holder that makes it easy to keep the filament straight while measuring. It is 100mm measuring from the backstop to the beginning of the notch line as shown in the pictures. I included two versions. 1. the backstop is even with the end of the tunnel for the filament. You cut the filament then slide it in and it will rest even with where you set your calipers. 2. the tunnel goes all the way through. I use this on my direct drive by setting it on top of my extruder where the filament goes in. I mark a line on the filament from the backstop of the bowden holder. Then i extrude 100mm and see how far down the line goes.
