To animate your pools in N or HO, here is a waterslide with its staircase (swimming pool not included)

The waterslide is to be print in one block (1 file excluding stairs), in its final position.

The printed toboggan is surrounded by supports after printing (see photo), which should be gently detached: I successfully used a small flat blade passed between the zig-zags supports and twisted to detach these supports.

->> Everything is to be printed scaling at 10% the provided files for 1/160 (N), scaling them at 18.39% for 1/87 (HO). The toboggan and the staircase are compatible with a print volume of 20cmx20cmx20cm. Printed in PLA, "everywhere" zig-zag supports, 100% filling (for N), brim 8mm, layer thickness 0.16mm.

The staircase itself is in two parts "staircasedown" and "staircaseup".

All the other files are the railings and pillars, intended to be printed flat (the flattest side against the bed), which allows a very clean rendering without a lot of post processing for cleaning the parts (print with a "brim" of a few millimeters, the nozzle not too close to the bed).

Staircase assembly :

1) glue the top and bottom halves enclosing in the middle "handrailmiddle1" (central railing).

2) glue starting from the bottom, face by face, turning following the staircase, the parts of the external railing : "handrailext1" ... until "handrailext7"

3) finish the hand rail of the upper platform with the two small barriers "handrailext8" and "handrailmiddle2"

4) Position the support pillars from the ground. They are already connected in two blocks "baseright" and "baseleft".

"Purchasing is temporarily disabled" here but it seems to last, so the model is also available on another site (search "stl files").
