Bracket

The original bracket is too large cannot fit in my voron2.4.

the reason is 

1 when voron 2.4 's  base /bottom plastic panel has insulation material, the space is smaller. the original design cannot fit in.  the bracket height must be reduce by 1-2-3 mm.

2 when the heater bed has insulation material , the space under is a bit smaller, it's very tight and difficult to install and remove the original model. with this mod, it's much easier.

3 slightly improve the magnet hole to easily print and easily install magnet.

Print setting

ABS since very close to heater bed.

support is NOT needed.

Build plate blocker

this blocker has nothing to do with silicone brush bracket.

but since the silicone brush mod can block the build plate on right side, this build plate blocker can block the build plate on left side, also it has a side block so hopefully it can help to put the build plate in the center.

It works only for Voron2.4 250mm.

One good thing for Voron2.4 250mm printer is, it can use all popular and cheap and easy to buy bambu build plates in the market. (256X256mm)

you can modify the model to fit your own size. fusion360 file is shared.

change the parameter side_len to make it fit.

the exact size depends how you build the 2020 extrusion under heater bed

print setting

ABS with support.
