Nozzle brush and bed stop for LDO heatbeds

If you have an Voron Trident or 2.4 printer built from one of the LDO kits, your heatbed most likely has 4 slots in it - two in front and two in back - which also contain an unthreaded M3 sized hole. This design allows you to utilize those slots and the associated hole to mount a nozzle brush holder and a bed stop. 

The when combined with the nozzle brush holder, the bed stop together make it easy to re-insert your print sheet and have it aligned correctly. You can also just print two bed stops if you don't need the nozzle brush holder.

The nozzle brush holder is designed for the silicone nozzle wiper that Bambu Labs sells (product name: “Heatbed Nozzle Wiper - A1”). In addition to being very low profile, this silicone wiper is much gentler on your nozzle and will not cause issues with eddy current (like the Beacon) or inductive probes. Bambu sells them in packs of 4 for $3.99 (USD). They stick onto the holder. 

Print out of a heat resistant material like ABS, ASA, or PC. To attach the stop and the brush holder, insert an M3 heat-set into each (careful, there's not much surrounding plastic), insert into the slots on the rear of the bed, and secure with an M3x8 SHCS. I used some thread-locker to ensure the screws don't vibrate loose.

There is no bucket, as I find them pointless and an opportunity for a nozzle crash. I use the KAMP adaptive purging macro to create a purge line right before printing. I run a nozzle wipe macro after homing, but before leveling, and then immediately home again. I set the nozzle temp well below the extrusion temperature, but low enough to soften any ooze on the end of the nozzle (180 degrees C for ABS and ASA). 

As always, CAD source is included in case you want to tweak the design or adapt it for other purposes.
