Wall feed thru for a 50mm hose

For the 50mm feed hose of my rain collection system I needed a feed thru the wall of the shed. When I saw how complicated it would be, 4 transition points with the risk of leaks, and that I would spend close to 30€ to get these parts I decided that DIY is the solution. A left over piece of a DN50 HT-pipe and a printed flange. Much simpler than 2 hose barbs and a threaded coupler where I would still need a mounting plate.To prevent that the pipe gets pulled out I wanted a very tight fit. Therefor I spit the bracket which will be held together by two 4x40mm screws. To increase the grip two 4x20mm screws with the tips ground off can be inserted which will squeeze the pipe a bit.Printed in PETG with 0.3mm adaptive layers. 20% cubic infill with double lines, skirt and no support.As I had only yellow PETG in sufficient quantity I painted it with some brownish color which will also protect it from the UV-rays of the sun.Why not just feed the hose thru? Well, that's how it was but the hose deteriorates quite a bit in the sun and it is much simpler to just change the exterior piece when it has passed its "use before date" which is about every 4th year.
