Adapter for HT90 Inspection Pipe

I built a small exhaust system for my H2C and my H2S (with laser).

It is designed with HT pipes with a 90mm diameter. These are inexpensive and available at any hardware store.

With this adapter, I designed an adapter using the inspection pipe variants of the HT pipes that can be screwed onto the thread and fits the 100mm hoses from Bambu or other manufacturers.

The screw connection variant was chosen so that the outlet can be closed again if the printer should not be connected for various reasons. A normal T-piece could otherwise have been used just as well.

The 90mm to 100mm adapter ring is designed to mount the 100mm hose onto the 90mm HT pipe; this is only needed if the hose cannot be compressed to 90mm. My aluminum hose, for example, did not withstand this without damage.

Additionally, I used the following print files:

For the twist-lock adapter, there is a print profile for the original twist-lock to 100mm hose.
