DIY spool holder/print from dry box out of a 4L cereal container with an interior width of 90-91mm. More sizes coming soon!

Parts you will need for assembly are:

x6 - 3x10mm hex button head socket cap screws (fine threads)

x1 - PC4-M10 pneumatic fitting

x1 - 7/64 drill bit (to drill holes for spool holder pieces)

x1 - 5/16 drill bit (to drill hole for m10 pneumatic fitting)

x1 - 4L Cereal container with interior width of 90-91mm.

Assembly is simple. look at the pictures above and assemble the same way. Make sure to drill the holes precisely to match up the two sides the best you can. Use the outer side pieces as a template. If the two sides aren't perfect, don't worry the only way it wont work is if you're very far off.

The rod that holds the spool is printed in 3 pieces. A dab of super glue will hold them all together nicely.

DO NOT OVERTIGHTEN SCREWS OR PNEUMATIC FITTING! These screws are all screwing into plastic and will strip out if overtightened.

the 5/16 and 7/64 drill bits are slightly smaller than the holes so you may need to ream the holes slightly to get the fit you need.
