All the parts are printed with 20% infill, and I use an Ender 3. I usually have to sand down the edges due to stringing etc. According to your printer's over/under extrusion you might have to sand down edges, or add silicon tape to the bolt heads so they key into the bodies. I personally prefer to use a brim.
