Elegoo Mars Pro Heater Spacer and Mount

prusaprinters

<p>3d printer resins often perform better at higher than room temperature. &nbsp;These parts will enable you to add an automatic heater to your Elegoo Mars Pro. &nbsp;It heats the build chamber and not the resin directly, so in cold conditions you will want to pre-heat the printer some time before using it.</p><p>The Elegoo Mars Pro is obsolete and out of production (though we still use a number of them). If there is enough interest I'm happy to create new files for newer printers, but someone will have to send me the dimensions for the spacer.</p><p>Note: This design is seriously back heavy with the heater and control board mounted. &nbsp;It will lean back when the red cover is removed but will not flip loose. &nbsp;When the red cover is on it sits properly.</p><p>&nbsp;</p><p>The parts:</p><p>I do not remember what material we printed these from. &nbsp;Most likely PLA. &nbsp;I don't remember the specs but I'd go with 2 perimeters and 20% grid infill.</p><p>Part 1: This spacer fits between the printer frame and the red plastic cover. &nbsp;There is a hole in the back to accept the heater mount flange. &nbsp;There is a small structure to hold the NTC probe for the temperature controller as well. &nbsp;The temperature probe is pushed though the back to rest on the scaffold and zip tied in place.</p><p>Part 2: The heater mount is designed to accept a 12/24V heater and a W1209 temperature controller board. &nbsp;There is no good orientation to print this part so matter what you'll have to use support. &nbsp;We printed these with the surface that mates to the heater down and had good results (use support). &nbsp;The screws that attach the control board are just screwed into the plastic mount and will self tap.</p><p>Part 3: The spacers are to keep the back of the control board from being mashed into the mount. &nbsp;We had planned on going back and adding built-in spacers to the design but never got around to it.</p><p>&nbsp;</p><p>Bill of Materials (includes affiliate links):</p><p>1x &nbsp;Spacer (3d printed)</p><p>1x &nbsp;Heater Mount (3d printed)</p><p>4x 4mm M3 Spacers (3d printed)</p><p>1x &nbsp; Heater. &nbsp;The heater we use is this one: <a href="https://amzn.to/3aDWQQT">12/24V Heater</a> (about $23). &nbsp;You can get a similar one cheaper on AliExpress if you're willing to wait. &nbsp;(I'll try to find a link to post later.)</p><p>1x &nbsp; Control Board. &nbsp;The W1209 control board that we use is this one: <a href="https://amzn.to/3OcL6CQ">Heater Control Board</a> (about $18 for 6). &nbsp;Again, I'm sure these are cheaper on AliExpress and I'm sure you can find fewer for more per part on Az as well.</p><p>1x &nbsp;Wire tie to hold temperature probe</p><p>10x M3x8mm cap head screw (Longer will work too.) * &nbsp;**</p><p>6x &nbsp;M3 hex nuts **</p><p>Additional cable ties to do some cable management can't hurt.</p><p>&nbsp;</p><p>* The control board mount is designed for M3 screws to drive straight into the plastic without nuts. &nbsp;If you want to substitute the M3 screws for whatever comes packaged with the control board have at it. &nbsp;We won't judge.</p><p>** We purchase most of our fasteners from <a href="https://www.boltdepot.com/">Bolt Depot</a> (in the USA, non affiliate) because we buy a lot and they're well priced. &nbsp;If you just need a small amount look for something like this <a href="https://amzn.to/3AJFhcV">M3 cap head screw assortment</a>. &nbsp;It's way more expensive per part but we've gotten these kinds of assortments when we need something we don't normally stock and need it right now.</p>
