Hmm… maybe a large shoe that has an “internal” structure to it that allows it to simply slip over the top of your actual shoe would be more comfortable. Or something like the old quad rollerskates that have the frames with heel and toe clips that fit over shoes so you can put on/take off quickly and easily.
Otherwise if you check http://www.smoothon.com they have life casting kits for molding body parts and videos that show how to do it.
Floral foam is also a nice squishy material. It’s rigid but will permanently crush under pressure and hold a shape. It could be a decent enough impression to start from but I have not tried it.
So an update on the home made arch support… On-foot 9 continuous hours today and the pain I usually get in the tendons in the front of the ankle (after I’ve relaxed a bit after hours and have a chance to stiffen up LOL) has been relieved. I can actually walk now instead of hobbling 'round til circulation gets going and muscles loosen up again. Score!
It’s also a little flexible and somehow produces a slight fart sound every step… Double Score!! I keep it!!
It is mains power supply that has an isolation transformer to allow safe working on live equipment, a variac to allow the voltage to be varied and a digital panel meter that shows voltage, current and power. Two 100W light bulbs in parallel can be put in series with the output to provide current limiting in case the DUT has a short. There are jack sockets for attaching my Mooshimeter if I want to log the current and voltage or view it remotely on my Phone.
I modelled every part in it except the wire, sleeving and ferrules in OpenSCAD, so is all 100% parametric script.
If I had my GF I intended to make the top and bottom panels from Delrin and the sides from acrylic. Instead I milled it from DiBond as that is what my router is set up for. Having metal skins meant I had to earth all six panels and then make sure everything inside was double insulated. It would be safer in an all plastic box.
I fixed it in the model but because the meter was designed for thinner panels I hot glued it in. I would have to dig it out and desolder the switches and sockets and then rewire them again so I am leaving it for a rainy day.
