Ender 3 modular Hemera mount (no X build volume loss)

thingiverse

# Ender 3 compact mount for E3D Hemera - The aio mount version(recommend) will keep the x offset of nozzle unchange and maximum the X build size is 235mm. This version only use 3 m3x7mm bolts to mount the Hemera to the plate. - You will need to change the x build size to 220mm if you are using the "compact" version. - 4020 fan mount is based on Joe Casha's design on myminifactory but can be use without applying glue. The "lower" fan duct version is 1.5mm lower. ## Update - Updated v4fix3 based on EricE555's recommend. ## Requirement - 2 M5x30 hexagon head bolts to mount the mounting piece to the base plate. The bottom bolt slot use the stock bolt and nut set in the same orientation. You can use the wrench to keep the bottom nut from rotate. - 4 M3x7 button head bolt to mount the Hemera to the mounting piece. - There are 4 slots for optional M3 square nut. These slots can be used to mount cable router or LED. - You will need flat head M3 bolts to mount the 4021 fan duct. - Also check the troubleshooting below if you have problem. ## Probe offset - Offset for 4020 fan and fixed bltouch mount(side) : <code>#define NOZZLE_TO_PROBE_OFFSET { 61, -16, 0 }</code> - Offset for 4020 fan and fixed bltouch mount(front) : <code>#define NOZZLE_TO_PROBE_OFFSET { 5, -45, 0 }</code> - Offset for AIO mount <code>#define NOZZLE_TO_PROBE_OFFSET { -33, 1, 0 }</code> ## Home offset - Compact mount version <code>#define X_MIN_POS -21</code> <code>#define Y_MIN_POS -16</code> - AIO mount version <code></code> <code>#define X_MIN_POS -7</code> <code>#define Y_MIN_POS -16</code> ## Troubleshooting - From EricE555's comment <code>I used a 30mm M5 hex head bolt for the bottom roller just like I did for the top. If you do that you use a nylock nut on the back and it sticks out too far and hits the gantry before you hit x endstop. The solution was to use the nylock nut in the printed part where the bolt head would go. Then I used the stock button head bolt from the back side and all worked as expected. </code>
