Not sure if this would be best in the 3D printer section or here but I thought I would share this bobbin rack case that I made up today. I have attached a stl file so it can be printed out if you like. I used a 20% fill with .8mm shell thickness settings on the printer. It uses 108 grams of filament at that and in Oz that's about $4.00 worth. It holds 49 bobbins and the L is 172mm x 125 W. The hole size for a bobbin is 12x23mm.

The hatch area is the gap area needed between bobbins to get your fingers onto each side of the bobbin to remove and replace easily.

Works good .....I think I'll make one for the big Cowboy ones next. Am working on a snap together zip installation guide at the moment which all going well I will finish this week end.

Cheers Brian

Very well done with the spacing to allow removing the bobbins!  Maybe can add a magnetic plate underneath the box to hold them in place when you accidentally flip over the case?

One more design idea (Constabulary's idea) with a magnetic tool holder on the bottom:

Nice! Thanks for posting this Brian. While it probably should go in the 3D section I think things like this should be in here too as I'm sure that many who might be interested won't think to look there.

Please feel free to post any designs to do with sewing machines, more to add to my (growing) collection of possibly useful files.:lol:

Only problem with that one gigi is that I have some bobbins that are aluminium! (But it would be simple to make).

Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500.

I was excited about the magnetic strip idea until I also realized that all of my bobbins are aluminum! Why hasn't someone invented an aluminum magnet yet?

ABS or PLA and how do you prevent warpage?

I haven't yet done it, but I will :innocent:

For the 'clones', I like the idea of a simple piece of wood.  If my drill press hadn't pooped I'd be done ;)  Few things to get organized around here, and then I'll put one up.

I suppose the 'trendy' thing to do is to post all over social poo trying to bilk leather workers into buying yet another item, or plans for an item. But maybe I'll just post a pic and a tip, and you can do what you like.  Note you will need:

  • something to drill with (hand drill might be easiest)
  • small twist drills, 1/8" and 11/64"
  • 1" spade bit (you could do with a 15/16" if thats what you happen to have)
  • ruler and pencil
  • block of wood, size dependent on number of bobbins retained
  • couple of #8 screws x 1" (or 1 1/4")

I wondered if anybody was going to point that out.

Brian,

Great idea and very well done. Since your doing it with a 3-D printer you could add a hinge and cover for it. I know if it was me I would end up knocking it over and have thread trails across the floor.

I thought about a lid but to be honest the cylinder machine that it will live with gets use every day and changing bobbins happens a lot so I thought it would just be a waste of time. with its flat base I don't think knocking it over is going to happen but I guess it could be stuck in place with double sided tape or something.

Pla and a heated bed run at 65 degrees C. The plate is cleaned well with Isopropyl alcohol before every new print.

Constabulary's idea looks good but I don't think the magnets should be needed at least if the 2 ends were blocked off. Might be a bit easier to knock over and lose them though.

Yes ...that was my thinking as well and I suppose it should be there as well perhaps as a link or something.:dunno:

Not my design - just a DIY I did. The original afaik is from GRABOBBIN. So far I found no better bobbin holder than the magnetic ones. I soon want to make some for different size bobbins as for 132K´s, 29K´s, 45K´s and the like but need some larger router bits... But thats off topic here.
