revised to v1.3- drip tray added to help prevent leakage. Bolting arrangement amended revised to v1.2 radius corners to help with sticking to build bed, two end recesses added to allow for a screw driver to be used to prise the templates apart. http://youtu.be/OaK46BK0zEY This is Based on the vibration dampening balls i already use , used on multicopters to isolate vibrations to the gopro camera range (will work with others). its a rough design, i will comeback and tidy up the design of this, once i get chance.i would like to have it hinged and a few other minor tweaks to make pouring the silicone in to the mould easier this is a version v1.3 the photos are the results of my v1 attempt, which came out well for a first attempt at moulding, but i modified the files a little, based on my first experiences. bolt the two parts together with m3 bolts, don`t over tighten. mix up your silicone and catalyst and pour. i used 50g of rtv 2020 silcone/catalyst as a guide of quantity checkout how to make the rtv silicone mix on google etc, there is plenty of info on there, you can see from my attempt, that i had too much air get in, this was totally my fault due to it being my first time using this silicone mixing. i know my next attempt will be far better, now i know what i am doing. i used medium hardness silicone as a guess, i have not tested it in anger yet but i will get round to it shortly.i printed with cura with a high %infil to ensure the detailed form was not lost. printed with pla and a layer height of 0.2.
