A suction side adapter for the Scheppach NTS30 wet and dry vacuum cleaner. I couldn't find one that matched my vacuum cleaner anywhere, so I made one based on the original one.

It is specifically designed for original hoses with pipe fittings, or in my case, for a longer hose purchased on Temu with the same end fittings, for connection purposes.

Both PLA and PETG should work fine. I've tried both, and the results were great. Maybe PETG is more durable.
