An industrial pull handle can be easily made wit a Ø20 aluminium bar and a 3d printer. This design is an example.
Aluminium bars and covers for it can be found on most home improvement and DIY stores quite inexpensive. A tube cover is provided on stl in case you forgot to buy them as I did.
This design is for a Prusa Challenge so hexagons are the main character and are made on black and orange. Actually, historic Prusa Ngen was used and it will look great on my office.
