Top mounted linear rail printed mount
🕑 Added 2024-09-29 02:42:55 +0000 UTCHad a metal mount option for such setup (whambam backplate).
You now have an initial fully printed version of a top linear rail mount.
Hasn't been tested yet, so the end stop may need some adjustments
I personally prefer the front mounted rail setup, so won't be trying it, but should work well as this is based on the Orbiter3 setup I made recently.
There is a minor limitation, for rear motor extruder setup like orbiter, and sherpa mini, they would need a simple 4~5mm riser as the motor would hit the back. Front motor setup won't have that issue,
This would use the rail version of the Apollo backplate, and is compatible with the extralock version of the apollo main body (highly recommended for such setup)
there are four screws as if installing the apollo to a front mounted rails, but for an overkill setup, there are 4 screws going from the back as well, likely unnecessary but it's there.
will need heat inserts as usual
you can use m3x10 or m3x12 screw to secure the apollo to this backplate.
as for the X endstop not sure yet what is needed, but chances are the one in the apollo zip files will work, likely the linear rail X motor block one.
the rest is hopefully intuitive, if not don't hesitate to go on discord (I'll be unavailable next week –first week of October , taking some needed vacation, but I'm sure the wonderful community on there can help you until I get back)
============================ RISERS ============================
Riser:
As an alternative to printed riser you can get metal ones

There are multiple combination that can be done.
First number is the amount of t-nut mounting point in the back, and second is number of point for heat inserts where the rail will be secured to.
The simplest is the following and should be good enough.
2x2 - 3x3 - 2x2
If you want extended support under the rail you can do
2x3_left - 3x3 - 2x3_right
Or
2x4_left - 3x3 - 2x4_right
I included more size if you want to play around or have larger printer and need different combo
