Description
It's been unreasonably cold here in Florida lately, so for the first time, I've had some warping issues printing ASA (my primary filament). Anyways, I also wanted to get slightly higher chamber temps. I had used a single 100w heater in a previous MK3S chamber I had, and a dual 100w (200w total) heater in another MK3S.
I designed and printed a mount for a single 100w heating element plus temp controller. It's a standalone unit - requires nothing from the Core One electronics.
First thing I needed was extra space to mount it, so I flipped the left side panel inside out. Then, what you see is what you get. Don't forget to tie the thermistor somewhere up high - I chose to tie it to the bundle of wires on the left side, rear of the cabinet. Then make sure the wires are out of the way of the build plate. 3mm nuts and bolts for the heating element, 6mm nuts and bolts for the bracket to side panel.
Does require drilling a couple 6mm holes in the side plate to mount it, you could redesign it for magnets if you so inclined. I also drilled a small hole (and insulated it) for the wiring.
