SFP/SFP+ box, customizable

thingiverse

I liked the original, but wanted to make sure that it would be a nice and tight fit, so I have been reading the SFP MSA and measuring my SFPs to make a it a good fit with as tightly packed modules as possible. The slots have gotten identifiers (1A, 1B.. 5D) and a paper slot so that it's possible to write on the front what the contents are, so that you can see what's in the box without removing each module. ## Changes: - Designed it to work with 0.3 layers. - Tweaked dimensions according to SFP MSA, as well as printer error. - added text on top to identify slots - added text on lid (number of SFPs in box) - added paper holder in front - added chaining mechanism so they can be connected together in a line. - added notches to avoid conflict with SFP latch mechanism - Designed to fit with copper SFP heads, especially height and length wise. - Combined the .scad files so that parameters can be tweaked while keeping the lid and box in sync. bottom()/top() lines must be rendered separately, or offset and rendered together. - Tons of parameters have been added to the .scad file. Not very well documented, though. ## TODO: - Should add some round feet at the bottom and some corners on the lid to make them stackable - Split SFP / QSFP version ## Recent changes - QSFP version! However it has not been printed and tested yet. I recommend printing a few mm upside down to get a plate that can be used to check if the model will fit. Let me know please :) - 14 -> 16mm spacing between the SFPs so that the GLC-Ts should fit (head height / y dimension looking from the front) ## Before you print The tolerances are tight on this, so print a test cube, modify the .scad or do some XY shrink tweaking in the slicer. Measure your SFP heads: * Width max: 15.2 * Height max: 14 * Length max: 25 (This is measured from the so-called positive stop, the next thing the slot hits after the latch. It includes the protective rubber bit) I think this will fit basically any and all fiber SFPs. I'm just unsure if there still are some copper SFPs that might be too big. Let me know if you find something outside of this spec :) a 2x5 version will probably print a lot faster and may be enough depending on your needs.
