ok guys I'll try to make this as simple as possible. the case i used was the axigear 16x13x6 from amazon(i chose this for it's mostly flat design). d-ring tie down anchors, and askuko 56 inch shoulder strap(other straps would not fit the d-rings). lar-me 2 inch rubber grommets. odontomed2011 6'' stainless plier. gcode files are good to go for the ender 3. I had to scale the stl files to work, so I will give you one axis just do uniform scaling. the velco strap holders I used can be found here https://www.printables.com/model/634010-velcro-strap-20mm-holder. I have a list of bolts, but you may want to got to your local hardware store and double check the sizes. I had to reem out the holes on the velcro holders. everything else was very snug.
The shopping list
1 ¼ inch 20 tpi x 2 ½ inch (pump bolt)
4 6-32 x ¾ (velcro hangers)
8 ¼ inch x ¾ (bag hangers and pump bracket)
2 10-24 x ¾ (d-rings for shoulder strap)
8 5/32 x 7/8 (washers)
if I missed something let me know.
