Reinforced dry box 8mm adapter inlet

This adapter modification is based on the model https://makerworld.com/en/models/2378745-dry-box-inlet-m8 and solves the problem of the 8mm diameter inlet thread walls weakening, causing it to break even with minimal force(even before tightening on a dry box).

Solution details: weakened walls of the thread reinforced with extruded tube till massive body part, but left space for secure fixation of the PTFE tube in the center.

Fully compatible with the other parts from the original design. Printed and tested using BambuLab PETG-HF.
