If you built a MK3/S from a kit, the one tool missing was a 5.5mm hexagon wrench or socket. Print your own socket in PETG or Prusa PC Blend. Fits 1/4" drive hex tools. A driver handle is included.
PC Blend is not difficult to work with. Bed warm-up (110C) takes longer and glue stick is required. Files include three STLs and one sample print file for PETG.
The author marked this model as their own original creation.
