Anycubic I3 Mega Boden Fixed Spanner

thingiverse

This modification (new part, fixed spanner) allows me to print with flexible filament (tpu), an almost impossible task with the original version, because the distance between the rollers and the hole of the original part is very large. I used a pneumatic union (pneumatic fitting) with a 10mm thread and as the dimension of the piece imposes some dimensional restrictions, I used an M8 nut in which I enlarged the hole to 9mm and opened an M10 thread because, given the forces involved, I think that the plastic is not resistant enough to hold the pneumatic union. Two of the opposite vertices of the hexagonal nut must be filed for the nut to have a dimension equal to the thickness of the piece.
