Last crawled date: 4 years, 2 months ago

Adapter for 2nd version of Subea mask (the one with larger, transparent shaft) to 2x22mm filters (ISO 5356). Exhale duct caps are integrated in the model.
Filter can be interference fitted and provides a good seal however I would advice use of o-rings. Channels for 21x2 o-rings are included in the model.
0.1 - initial release
0.2 - extending opening by 0.4mm diameter wise and tapering outwards up to 18mm, retracting caps 0.5mm deeper into geometry
0.3 - added channel for ridges (0.5x0.5mm) on the bowed side
0.4 - fixing curvature on bowed side of receptacle (0.5mm proportional towards inside of opening) added channel for ridges on the other side
0.5 - further adjustments to curve on the bowed side, filters receptacle 1.5mm deeper
0.6 - 15deg angle of top portion for better clearance from the top of the head - TESTED POSITIVE IN ABS - MOVING TO v1.0
1.0 - STABLE RELEASE
Dismounting forces:
over 25kg on mask-adapter interface along the axis of the shaft
~17kg on adapter-filter interface along the axis of the shaft, no o-ring (higher force can be expected with the presence of the o-ring)
