Description

Next step is to get more capacity (tip from the guys at www.makerpoint.nl).
Getting hoses around the two crossing print head suspension shafts is not too easy, so I tried to squeeze in 40mm fans. No time to try it yet, but it should fit. Needs a bit more distance between the x-y stage and the table, so I added an adapter piece.
Another feature I added is a heat shield mount. Can be made from a beer can or some other 0,05-0,2mm metal plate.

I found a lot of 40mm fans so choose one that's easy to get. Maximum thickness 10mm. Bolt pitch is standard 32mm.

UPDATE a
I made some bad presumtions on how the print head looks inside, so I had to redesign the adapter plate. Now you can mount it without taking all cables loose.

UPDATE b
I wired the fans and they hardly turn :(( Only at 80% fan speed the rotate a little. Or if I short-circuit one, the other runs very fast at 80%-100%. The strange thing is the new fans are 0,05A whereas the original ones are 0,1A. Puzzled (and pissed).

UPDATE c
The fornt part is blocking flow through the permanent cooling fan. DO NOT USE. I will make an improvement soon.

I really like this design, I barely use fans to start with, but it should definitely keep the original fan size. I just want to avoid scraping on the side wall when homing the nozzle.
