Mk10 HotEnd Heat Block Insulator - mould for silicone

Mould to make your own silicone insulator for mk10 hotends with heat blocks measuring 19x19x12.5 mm (Wanhao i3 etc.)

I was seeing a temperature drop of my hotend when the cooling fan was on maximum. Using this silicone insulator has completely solved the problem. It also helps the hotend heat up faster and maintain its temperature.

You will need:

Curing liquid silicone rubber ~ 15 g
4 m3 nuts and bolts if using the 2 part mould base
Vaseline for mould release if using 1 part mould ba
