I printed and my wife loves it and I used the screws and nuts that you said too use but all metal and it works great. Thank you for the great item to print. I also printed in PLA black and it printed fine no small holes for screws or nuts

Settings I used Cura 4.2.1
Tronxy Black PLA
Nozzle: 0.4
Infill: 100%
Layer height 0.16mm
Raft : YES
Supports: NO
Bed Heat: NO
Extruder Temp: 206 C

Can you make a version of the one with no logo but with less deep holes for the nut and the screw?

Just started the print, looks awesome! Thanks so much! Just wondering, has anyone tried to put a flash drive on this?

Comments deleted.

Is there a version of this that will fit non-metric size screws?

The hardware stores here don't sell any small metric screws or nuts, just a few metric bolts M5 and bigger.

Try an Ace Hardware, they usually have the best selection of metric hardware. Home Depot is decent, and Lowes is in last.

what size M3 screws and nut need to be?

That changes depends on how many keys and washers you plan on putting in it.

I don't have a heated bed to keep the ambient material temp up so sometimes i have minor bonding problems. (printing multiple parts simultaniously that is) I get too much cooling in between layers occasionaly and it would be benificial to me if someone could post the right and left sides as independant files.

I made this but the nut holes are just a teensy bit too small for the nylock nuts I used, resulting in me having to jam them into the PLA, which sort of stripped them. I'm going to re-print at 104% as a second try.

the hole is 3mm yeah, the thread isn't ;)

M3 literally means that the outside diameter of the thread is 3mm. So yes, both the thread and the nuts are 3mm.

I am using these washers. they are for a number 4 screw, and work perfectly with the M3. They are pretty wide so it helps with keys that have oddly shaped holes. McMaster part # 92217A369

The screws are near impossible to find..had to use phillips head, but consolidated 2 carbiners full of keys. My only suggestion is the ring holder is a little small and gets in the way unless you use a ball chain, and you have to have an even number of keys or they flop around and the unit is crooked.

If you have a odd number of keys you can just add a couple washers to make up the difference to keep things evenly spaced.

great job by the way! just a few notes, thanks for the tips!

The only problem I see is with quick removal and car keys. Cool idea, but I may give this some additional thought before printing.

I don't see how you'd get a car key to fit in there anyway since they have so much larger "handle" end with the chips (and now buttons)...but if you had an ancient car that you could get a flat key why would you need to remove it?

for an alternative I've used this for some time

BladeKey(TM) - Key Organizer

For all those times I've thought, "Man my journey through airport security just went far too smoothly for my tastes". Haha just kidding, this thing looks awesome. Printing now.

do you use slic3r for this? I printed it but the holes are way to small for the nuts and screws to fit in... any suggestions?

Yes I use slicer. I have sliced it 3 different times with perfect results each time. I can snap in the nuts by hand and there is a little play for the socket head to handle off center heads. You might need to calibrate your extruder better

Have you calibrated your extruder? And have you measured your filament diameter and entered the precise measurement into slic3r?

haha I was in the middle of making this after I saw it on instructables. You beat me to it.

Any chance you could provide one without logo, which would allow us to put our own on it. :)
