Needed a nice compact bracket to support the E3D Slimline Nema 17 Motor (it has a 26mm long body) they use for their Titan Extruders.
I wanted mine mounted this way to reduce issues for the extruder to bring the filament off the spool (which is directly above).
Inspired by **jnaulets** great design https://www.thingiverse.com/thing:829038 but here I have taken away the neck, cut away a section for the 4-wire connector socket and created several versions.
*Nema17SlimlineBracket* and *Nema17SlimlineBracket _v2* are similar except the M3 holes to secure to the frame are different distances apart - I prefer the *Nema17SlimlineBracket* as it's easier to pick up the M3 bolts which you have already put into the channel (I hope!) and stacked on top of each other (I find a little bit of Blue Tack in the channel helps keep the nuts handy and not slipping down to the bottom).
*Nema17SlimlineBracket_v3* has a channel for the wires for the stepper motors at the bottom of your frame - I haven't tested this but as long as you are ok with printing overhangs then you should be good. I am not that precious to have to hide the wires everywhere ;-)
*Nema17SlimlineBracketEnd* and *Nema17SlimlineBracketEnd_v2* are similar except v2 has a little nub to fill in the gap of the cutaway for the 4-wire connector - again depends how stylish you want it to look - have a look at the photos. If you want to save the tiny bit of filament than print the *Nema17SlimlineBracketEnd* version.
It is snug as the brackets fit in the channel that runs down the corners of the motor (you should be ok to push but if it's too difficult then run a knife down the edges of the print of the interface with the motor) and stops is flopping around, however if there is a little bit of play then put a thin sliver of rubber in there to fill the gap - if this is a common problem then I can make a version of the bracket a couple of mm shorter.
I printed these at 40% infill. 0.2mm layer height. PLA.
You will need: * *3xM3 8mm* bolts for attaching to the OpenBeam. * *2xM3 20mm* bolts to attach the end to the bracket.
As always tighten well but not too much - I hate hearing that **crack** when you turn half a turn too much...
Screw the bolts through once before fitting to make things easier for the actual fitting.
