Stians E5Plus Hemera mount - 27mm Piezo and BL-Touch

thingiverse

I could not find a mount for E3D Hemera to my Ender 5 Plus I liked. Using the original metal back plate was too constraining. So it had to go. Not sure how solid a plastic part with an eccentric nut will be. <h3>Update 2020-10-20</h3> I have been using this design with good results for 2 - 4 weeks now. There are some improvements in the uploaded parts I have not tested yet but I believe they work ok. <h3>Main objectives</h3> * KISS (having a hard time adhering to this sometimes) * Supporting both BLTouch and piezo element as z-probe * Full or near full build area (not there yet) * Design files will always be available (hate when you only get the STLs). As long as F360 (free) supports exporting to STEP I'll export this in addition to F360 files. <h3>Printed parts</h3> * Adapter plate replaces the X-carriage extruder mount plate * Piezo yoke is an experimental piezo mount to "catch" the pressure between the two upper Hemera mount screws. It works as a yoke to to push on the piezo on a single point. It's designed to hold the piezo element with o-rings (22x2 mm or 22x3 mm) or a similar rubber gasket. The o-rings should also give proper pre-tensioning. * Experimental wedge belt stopper to grip the belts. No extra parts other than the wedge. More tension on the belt should grip it tighter. This has worked flawlessly over a month now. * Belt bump is an optional part to push the belt towards the v-slot so the movements will be more linear. I don't like that the belts are at an angle as it will make the geometry slightly wrong. <h3>Areas of improvement</h3> * Belt routing through the carriage is a bit cumbersome to do the first time but it seems to work. Considering having two separate wedges instead of one for both sides. * Fan shroud optimization of air flow. Seems to focus before and below the nozzle tip. The two funnels could be spaced wider. <h3>Other parts</h3> * E3D Hemera * 135 cm or longer GT2 belt (stock belt is too short) * 4020 blower fan as replacement of the stock parts cooler * Piezo z-probe (optional), https://www.precisionpiezo.co.uk/product-page/copy-of-precision-piezo-universal-z-probe-kit * O-ring 22x2 mm or 22x3 mm * 6 M5x10 washers (shim the 3 stock M5 bolts for v-slot wheels) * 1 M5x20 washer (the M5 lock nut needs a washer as the "eccentric hole" is a bit big when 3d printed) * 4 M3 x 20 mm * 4 M3 x 14 mm * 2 M3 x 8 mm (could use 6 mm or longer) <h4>For everyone uploading designs</h4> **Please share your design files or proper model files, not just the STLs** Online project (haven't tested this yet.
