Parametric RAMPS 1.4 Enclosure with Offset Mounting

This is a parametric RAMPS enclosure with various tunable parameters. The included STLs are specifically for a RAMPS 1.4 with LCD board and a 40mm fan mounted on the interior top, with a mounting offset for a SeeMeCNC LaserCut Prusa i3 frame. The SCAD is easy to edit for other setups.

This enclosure provides 4 screw mounts on the rear of the box to secure your RAMPS board. Once mounted the plugs should align to the bottom openings. There's a slot on the rear side of the box to pass through all your printer control wires, keeping wires out of the way while allowing you to shift things around. By default a 40mm fan mounts on the inside-top, pulling air from below.

This box has separate mounting holes for the box itself. This is a tunable offset, originally intended to move the box out of the way of my X motor. The exterior risers ensure that the box clears the bottom threaded rod on my i3. The space behind the box is useful for the x endstop and motor wires to pass through.

When the box or lid are printed in translucent PLA it gives the status lights a cool glowing effect.

Print instructions

There are two options for making this box. You can make the whole box, plus the cover, or you can make all the sides separately, then glue them together (and still also make the cover). The box should be reliably printable as a single part on a well-tuned RepRap, but printing all the pieces flat makes better walls. If you decide to go that way, I recommend using hot glue for PLA, or superglue and acetone for ABS.

The cover is intended to snap on and be relatively easy to pull off when you need it open. If the clips don't hold perfectly, you can put tape over them to fatten them up, or try printing wider clips by messing with the SCAD file.

Notice that the SCAD files are set up in a cool way. Each file renders as a separate part when opened in a SCAD editor, but the "whole" file includes an override before including all the parts, so they align to the right position for the full box. A simple trick, but one that makes it easier to split up parts into separate files that each manage their own stuff.
