Mask base adopted to easily print with a modular cartridge like filters with advanced mount system. This scaled-down and adopted version from https://www.thingiverse.com/thing:4273471 adult version. The main body and back part of the cartridge were scaled. It has the same filter cap but the back part of the filter cartridge is adapted to mount to smaller mount fixer. The rest parts are identical.
This version has ~ 100mm from top point till bottom - from an upper point on the nose till the bottom point on the chin. Adult one is 130mm
See rest photos and instructions in the adult version
(no supports, see correct orientations on screens)
Feel free to remix and add other filters
Use 14 pcs M3 x 8mm bolts to mount all
Use elastic strip 7-10 mm
If want to let your ears relax use Y splitter part (see photos shown for kids version)
Filter mount holder is constantly fixed by bolts (don't want to use any glue)
It was done also to get the best orientation while printing threads
Add filter infill using any suitable material with diameter 55-50mm
Video demo for adult version(was done for revision 1 that had no Y splitter and without improvements, here uploaded improved revision 2)
