Teenage Engineering EP–133 K.O. II / EP-1320 Medieval / EP-40 Riddim Protective Covers

I wanted a cover/protector for the EP-133 so I can throw it in a bag for travel. I grabbed the official bag from TE, but it's a soft bag, so I made a cover to go along with it to protect the fader and knobs from crush damage.

My design uses my Prusa XL to make the shell primarily out of PLA and TPU for the parts that actually make contact. It’s friction fit but it works for my needs and stays in place in the bag.

There is an XL 3MF that I used to print my case. Since I was doing multi material, I added some TE style graphics. There is also a 3MF for the MK4. The cover should fit fine on a MK3/MK4 or X1/P1P/P1S build plate. No supports needed.

I’m not sure if you print only in a hard filament that the surface of your EP-133 would be safe from scuffs or scratches from the points of contact. Alternatively you could print the entire case out of TPU. I did a version out of PLA/TPU and also one entirely out of TPU.

The silver logo version is the Prusament galaxy black and silver PLA with Overture red TPU. The one with the red logo is Overture red and black TPU.

8/8/2024 - I noticed the top corner near the switch is fragile, so I created a V2 with stronger corners.
