Is there a reason that a nylon washer isn't used...

[rlrcstr 1]

When assembling the hot head for the UMO+, the instructions tell you to leave a small gap between the wood and the aluminum bracket that actually holds the extrusion head.  I assume this is to minimize heat touching the wooden parts.  Leaving the space seems to allow a small amount of wobble in the head.

Is there a reason not to use a thin nylon washer and tighten the thumb screws to solidify the head?

Thanks.

The small gap is only temporary; you are supposed to close the gap by screwing the long screws tight a couple of steps later, after pushing in the bowden tube. This whole arrangement is so there some compression tension on the bowden-tube, pressing it against the white PTFE insulator.

Somehow I missed that bit... Thanks.
