Sliding Lid RAMPS 1.4 box by jman Nov 30, 2011

Description

I know, the last thing we need is another RAMPS box... but I wanted to put up the updated Sliding Lid Project Box, and demonstrate the new screw hole option.

I also thought it would be good to show an actual use of the parametric box.

The original box did not print the actual holes for screws, just screw blocks you could drill into. That was because I felt that printed holes were hard to get accurate, and this could lead to plastic cracking stresses. Now holes are printed as a star shaped hole, a bit like some masonry mounts. These will accept a lot of different screws and not stress out. There are now two parameters to separately specify the screw hole, and the hole in the lid.

I have made and assembled the RAMPS 1.4 box, but haven't had it in operation, so I can't be sure there is enough ventilation.

Hi!
The holes in both the lid and box parts are made through the "Sliding Lid Box" customisation routines. In particular "HoleInEnd".
Here is the first part of that module.

// Called by pbox to make any required holes in the end of the box
module HoleInEnd() {
// endround(x,y,w); // for round holes, X & Y give the centre
// endrect(x,y,w,d); // for rectangular holes, X & Y give the top left corner
endrect(38,27,24,10); // Power connector
endrect(43,24,2.5,4) ; // 'teeth'
endrect(54.5,24,2.5,4) ;
endrect(43,36,10,14) ; // DC socket
endrect(11,38,14,12); // USB connector
.

Does it not work for you?

The scad files don't seem to have the holes for power/usb included. Did I just miss them?

thanks, I looked around for almost an hour on my own and couldn't find it, now I can mount my ramps more decently :)

Instructions

Please see the original object for instructions, but really it is best to just read the OpenSCAD code if you want to fiddle.
If anyone feels something is obscure please let me know and I'll improve the comments!

With respect to the RAMPS box version, the stepper leads and other leads can come in the vent holes on the left, while the PCB stack slides in from the right, with the shield actually going in the PCB guides.
A 40mm fan bolts onto the lid, and so air flows over the stepper drivers and out the vents. You could add more vents even.
The lid has holes and vents for a standard 40mm fan, held in by four M3 * 16mm bolts.
Module HoleInLid has the code for this, and module HoleInEnd has the various openings for plugs, vents and cables.
I put a small strip of foam on the end section of the lid to hold the PCBs in place snugly.

I have printed the RAMPS 1.4 box components on my ToM, but on a HBP. There may not be room on the ABP.

The standard box is 90*60*35, with one pair of screw holes and two sets of PCB support. Just as an example, really.

Hi,

Awesome design!

Where can I find the holder of the box that is shown on the picture?

Thanks

That would be Thing 13556

Hi,

I'm new to this forum and found a lot of interesting project.
I'll like to create a plastic case for a smart camera that we designed recently.
I'm looking for a size 8 x 8 x 5 cm with couple of holes for cable connection. This one has a lot in common to my objective.
Can somebody help me?

I guess the devil is in the details, like where the holes actually need to go. Certainly you could use this box, and program holes in the end of the base part. Other boxes might be simpler or easier to print, if you don't need the sliding lid, or pcb slots.

Without holes, you could make a start with parameters like these...

// Outside dimensions of the box, and other structural dimensions
OutL = 203; // Length in mm
OutW = 203 ; // Width in mm
OutD = 50 ; // Depth in mm
WallT = 3;//2.1 ; // Wall thickness (mm)
// PCB supports are defined by the distance to the underside of the PCB, from the top external of the box.
// Supports for the PCB are ribs above and below
PCBgap = 2 ; // Slot size for PCB to slide into
PCB1 = 0; // Position of first PCB (0 if none)
PCB2 = 35; // Position of second PCB (0 if none)
PCB3 = 0 ; // Position of third PCB (0 if none)
// Screw fasteners are positioned by defining their centre
// They will be positioned on either side at that height.
Screws1 = 45 ; // Position of screws
Screws2 = 10; // Second set of screws

There's one RepRap question I don't see asked or answered enough… Where did you connect up the power to your electronics cooling fan? The build area fan is usually wired to D9, so it's not clear where to connect up a second fan on RAMPS (1.4). What was your personal solution?

jman on Mar 4, 2013 said:

There is a "12V-AUX" 2-pin connector on the RAMPS 1.4 board. I'm using that.

Awesome! I was thinking about something like this the other night, not realizing you had already done a sliding box kinda thing.

The fan grill is for 40mm I hope?

Skeining and printing now... :-D

Yup! 40mm, 16mm M3 bolts. (Instructions edited!)
