This is the bed holder, and other related parts from the upcoming Rev E release. I am releasing them now because they are compatible with the Rev D, so it would be a shame to keep them squirreled away!
Print Settings
5 top/bottom layers, 6 walls, 50% grid infill. Do not use classic wall generator, ever. Make sure to use Arachne!
Bracket: Still recommended to print in PETG-CF. However the upgraded geometry is now so buffed it could be printed in regular PETG.
Bed Holder: This needs to be stiff primarily, so I would again prefer PETG-CF.
Cups: These need ABS/ASA, they are right next to the heat source. I like to use concentric top/bottom layers because this part is a circle.
Rigidity Improvements
This project began with the new bed bracket, which is bulked up for extra rigidity, suitable for printing in plain PETG where PETG-CF is unavailable, and grew into multiple part redesigns. Also for rigidity, the new bed holder is 1mm thicker, and an additional 2mm thicker in the center. This bed must be used with the wrap-around tool head which has 1mm of extra clearance.
And more improvements below:
Integrated Rails
You can now slide on the bed and fasten the screws one-handed. You like to see that!
Edge Connector Reinforcement
The bed holder and bracket now contain a small feature to constrain the edge connector in all directions. Consequently, it's now harder to insert the bed, however the advantage is clear - the contacts of the edge connector previously acted as springs, causing homing inconsistencies because the bed is able to move up and down by .4mm. By surrounding the connector from all angles, we now constrain the bed and can get more consistent results.
FDM Update
By cutting a small slant in the rear of the bed holder, I made the bed more tolerant of printing inconsistencies. This small slant ensures that when tightened, the bed registers against the bracket, solving the issue of any gap between the bracket and bed holder.
One Less Screw
By using the new Bed Holder Cups with M3x20mm Countersunks, we accomplish the clean elimination of the M3x20mm Button Head screw.
Changelog
2025-09-03: Updated cups - Fixed wrong screw hole size, added .05mm clearance to edge.
