I have used and seen several commercial case covers, and they all had problems:
- synthetic fabrics cannot be repaired
- often polyester or easily-unravelling nylon
- One brand didnt even fit all my cases
- carrying strap too narrow; folds up uncomfortably under weight
- carrying strap clipped onto the case cover(!) These plastic or metal clips are the weakest link; if they bend or break, the case falls.
- Zipper fails easily, especially around the curves, and cannot be replaced.
Here is a case cover I had made by a local seamstress for less than $50.00 USD. It is heavy cotton canvas. Drawstring closure. The strap came from a medical-supply store; used for restraining patients in wheelchairs, beds, etc. I use an old belt as a compression strap wrapped through the carrying strap to keep it from ripping with the weight, and to keep the case from sliding out through the drawstring opening. The inside has been reinforced with a strip of seatbelt material to better support the carrying strap. It even has some lightly quilted padding.
I need to experiment a bit more with where the handle is attached (case isnt quite balanced) but otherwise, i love it.
Pretty good for a prototype!
