I moved to a new place on my own, and needed a simple, painfree and good-looking handle so I could transport my printer easily on public transport. I came up with this design, which utilizes four of the mounting holes in the top of the frame (easily drilled if needed) and it houses small Ø8mm super strong magnets to hold small tools! You need to print the handle twice so you can sandwich them on the 3-4mm frame. I used m3 bolts and nuts because that is the size of the holes in my frame, but the holes in the handle are m4. Pro tip: use some soft material sticker on the handle to make transporting your printer even more comfortable!
