Expo Ambiente Smart Set curtain rail holder

I bought a rather pricey Japanese wall set in Bauhaus only to discover the rail (Expo Ambiente Smart Set) has to be mounted with a couple special plastic snap-mounts (either to the ceiling or to an wall-mounted L profile), both ending up pretty far from the wall the curtain is supposed to cover. Normally it wouldn't be a trouble, but a Japanese wall curtain is completely flat. The mount allowed you to get only 17 mm from the wall, which felt too wasteful for the spot (a bookshelf) I was trying to cover.

I wanted it as snug to the wall as feasible and so I made my own snap-mount compatible with the rail, getting as close as 4 mm to the wall. The thing is, this rail is to be mounted only from the side, so you can't really align it to the wall entirely. Also the rollers that come with it are strangely tilted towards the wall, so those 4 mm is a pretty sure minimum distance anyway, otherwise the rollers would start scratching the wall.

The original mount has an elastic part, that allows for detaching the rail when pressed. I managed to mimic this capability, but my mount is mounted to a side (wall) instead of the original top (ceiling), hiding a screw behind the rail, with only a couple mm of the detaching part looking downward.

Due to the space constraints, the screw has to go through the elastic part, so its head has to be small enough to sink into the static part for the elastic one to be properly operational. The holder has a pair of leading “ramps” for an eventual contact with the curtain roller that help it ride over. Still it's the best to put the holders to places where the rollers don't really travel (or travel less), as an eventual contact seems inevitable (slightly disturbing the movement). It's a tradeoff for the space savings. One could put a 2mm more distance there and no contact would likely occur, but that wasn't my choice.

I printed the part on my poorly calibrated Prusa MINI+ with a rather generic and wet PETG using an oozing 0.6mm nozzle, but it all ended up pretty functional. The bottom of the elastic part is lifted from the base a notch (that's a must), so the print needs a bit of supports on the part sides, and an eventual sanding to get it flat when pressed. Nothing what a couple seconds with your faithful Dremel wouldn't fix.

I sliced the model with layer height of 0.2 mm and later with 0.15 mm (0.6 mm nozzle), both ended up pretty usable, although it's nothing fancy. Print in the default direction.

I wouldn't definitely recommend using anything brittle like PLA for this model, but you can always try your luck :D

PS: The middle photo is a bad print with botched ramps that nicely bump the roller coming over  ':-D. I left it in the middle to work as a soft stop! Genius! :D
