Mars 2 (or 2 Pro) DIY Enclosure Heater

thingiverse

This is a solution for installing a PTC heater inside the enclosure of a Mars 2 or Mars 2 Pro resin printer. It took me 3 trays on the Mars 2 to have all the parts. This solution is nice because the front half of the border comes off with magnets which allows you to leave the heater in place while removing the resin tray. When reinstalling the front half, it self aligns and makes the process very easy. I glued the 6 border pieces together as well as magnets in all of the remaining holes (link for magnets below). The PTC heater installs with #8-5/8 sheet metal screws. Future improvements might include a baffle and position mount to ensure the hot air doesn't blow on the temperature probe, a thermal fuse for if the fan fails (others have found the heating element gets very hot). Here is a video I posted on Reddit: https://www.reddit.com/r/ElegooMars/comments/s38p3v/temp_control_for_mars_2_or_2_pro_with_parts/ Here are links for the parts I purchased (sheet metal screws, glue, and a power supply that matches your PTC heater's requirements are also needed): https://www.amazon.com/gp/aw/d/B07GQPT9VG?psc=1&ref=ppx_pop_mob_b_asin_title https://www.amazon.com/gp/aw/d/B09F8SMZZB?psc=1&ref=ppx_pop_mob_b_asin_title Note: this is a 24V heater but 12V also work https://www.amazon.com/gp/aw/d/B07RPNJ2SM?psc=1&ref=ppx_pop_mob_b_asin_title
