Fire truck toy 3D print model

screw_ladder_base_sleeping_v1.stlFully printable - no glue - single color 3D printer

Fire truck toy I designed and printed for my son.

Print with a machine that handles tolerances of 0.3-0.4 mm, if it doesn't, things won't fit together, and the ladder peaces will most probably stick to each other. Print the screws and dies with a layer not thicker than 0.16mm (did not try a coarser one, so no guaranty that it will work...), I recommend 0.12mm.

For the assembly steps check the photos.

Hopefully I did not miss any stl files, if I did, leave a comment.

Some adjustments to the long/big parts such that the model can be printed on smaller beds (20x20cm).

1. I splited the side parts in two and connected them with two small screws.
2. Therefore do not print:
   • 1x - side_left.stl - white - turn 90 deg over X - no support
   • 1x - side_right.stl - white - turn 90 deg over X - no support
3. But print these instead:
   • 4x - screw_small_l12mm.stl - any - as it is - no support
   • 1x - side_left_back.stl - white - turn 90 deg over X - with support
   • 1x - side_left_front.stl - white - turn 90 deg over X - no support
   • 1x - side_right_back.stl - white - turn 90 deg over X with support
   • 1x - side_right_front.stl - white - turn 90 deg over X - no support
4. I cut the ladder to be shorter (220mm) such that it can be printed on a 20x20cm bed diagonal.
5. Therefore do not print:
   • 1x - ladder_in_out.stl - white - upside down - with support
6. But print these instead:
   • 1X - ladder_short_220mm.stl - white - upside down - with support

The model was initially posted on https://www.thingiverse.com/thing:3457842

I will be posting soon my new platform for a truck toy...

The model was designed with Freecad, I can therefor also upload the Freecad project file with it...

Update 04.2021: Because the axles and/or axle screws and the ladder base screws are breaking often (if also printed with PLA) I redesigned them similar to the other truck models. For this use this:

• axle_l100mm_new.stl instead of the original axle
• cap_double_rim.stl instead of the original screws
• screw_ladder_base_sleeping_v1.stl instead of the original lader base screws (prind directions as in the files) Check the last picture to understand what I mean.
