face mask ear saver ( for laser cutters )

thingiverse

NOTE: this is for laser cutters , NOT 3d printers ( a thought about using materials other than 3d printer filament, cut out existing recyclables) So i see some have made these already I made this last night, kinda looked at a model the boy scout in Canada made and one more recent laser cut one and I cut several last night ... several materials with the idea to use things that go in trash or recycle bin .. cardboard (not so strung, but if single layer is doubled could work) plastic of milk carton (too think but has real potential if doubled(thickness)) foam from meat packing (no strength at all but cuts ez) vinyl/pvc like from a blind shutter - yes , high strength - PVC must be vented OUT of the shop area ... The single layer cardboard cuts ok, without burning - and when doubled up could be useful as a throw-away ...( ok flexibility) - corrugated cardboard doesnt cut well and burns easily - not good foam meat packing- it cuts great , shows great detail - downside : has no strength whatsoever, handle with kids gloves (not very flexible either) .. u drop and end tong will crack by own weight milk carton plastic (ptfe?) - a bit on the thin side, doesnt cut great (kinda has overlapping melting issues) -excellent flex. --- but when double up would have strength - the same plastic sheet in thicker would be viable and reuseable --- A vinyl (or PVC) blind strip- about 1mm thick (1.5 or 2 would be ideal) has enough strength to be reusable and good flexibility --- cuts 'ok' ( may need a double run over) downside : fumes from PVC - extreme toxic - ABSOLUTE MUST to vent out of shop area UPDATE: I have (after seeing how week the foam cutout is) somewhat *thickened the tong base and *reduced the end tongs, total 6, this will reduce print time as well as make fittable as some beds /sw have a physical size was a restriction. feel free to comment for improvements not exactly 100% ideal but works, will cut out at 10mm/s in 1:16m:s of course this was slow and eazy without a bunch of air, with alot of air pushing and more power of course this time could be halved ... 2d cad was used ...
