heater with external on/off button

a simple heater mod for the Centauri Carbon but can be used with any printer. ive designed this with 10x20x5mm magnets. a 10 mm hole will need to be drilled to accommodate the on off button so the heater can be left in place once fitted. the heater holds the chamber nicely up to around 60°C (or lower if required, I use a wifi Temp sensor linked to a Smart Switch, but chamber temp can be set in the slicer and the extract fan will maintain the temperature). the button uses a 4.5mm generic pen spring but isnt required, I wanted to keep tension on the switch. The Top Vent also uses 10x20x5mm magnets and helps to push air around the chamber evenly instead of blowing straight up onto the belts/components Heater:https://www.aliexpress.com/item/1005010024954237.html?spm=a2g0o.order_list.order_list_main.5.51361802989U7U Magnets:https://www.amazon.co.uk/dp/B0DQXNH9MP?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
