Mushroom Roof Vent for waterless Toilets (e.g. BioToi) used in RV / Motorhome / Campervan / Wohnmobil

Most waterless toilets for RVs come with a 12V fan and a hose to transport the air outside somehow.

There were only pretty big mushroom roof vents out there that required a big hole in the roof of the RV.

Thats why I designed this one. Its made for a air hose with an outer diameter of 28,5mm (LAPP SILVYN® RILL PA6 7 https://www.lapp.com/en/de/silvyn-rill-pa-6/p/61746970 ) that came with my waterless toilet. If you need another diameter its necessary to create an adapter or do a workaround somehow.

• Easy to print - no supports needed
• Use M3 heat inserts to connect the main-body with the cover
• Use M4 heat inserts to fix the main-body of the vent with the body of the RV 
• use some rigid wire mesh (f.e. stainless steel) to keep insects outside
• use a proper sealant between the main-body and the roof of your RV!

Unfortunately I did not take any pictrues of the assembly or installation.

If there are questions i do my best to answer them!
