Some complete novice stuff here
Making the visor mold atm. Decided to make the mold through 123D Design to 123D Make, stacked slices printed to A3 and then cut with a pencil knife from 3mm cardboard, stacked together with a little bit of paper glue, cut some horrible parts out, one tube of wood filler, sand, another tube of wood filler now drying..
Will sand one more time and have 2 options atm. Either I will sand once, add one more tube of wood filler and sand that, or I will sand this, then put a layer of tape to smooth it some more and then add one more wood filler tube and sand it out. What do you think? which one would work best?
I'm not sure how I will do the flanges, they wouldnt be possible to do by vacuum forming since they go negative, I might cheat and glue some on. Blow forming seems so hard to get right. I will form 2 hemispheres with this mold and then the bottom part I will cut to the the size that it should be. One idea is to just raise the current mold a bit and vacuum form the flanges a bit deeper, then with a heatgun, form them to fit the lower part of the helmet..
Got myself some White ABS filament to print some stuff now, haven't had any time to do it tho.
edit: I have some 3mm acrylic and 1.5mm PETG, couldn't find any thicker PETG in this timetable, so I will see which one will work the best. the 1.5mm PETG might thin a little too much but I'll see.
P.s. Can you find my plate/mug from the first picture
