I increased the length and width of the holder for strength. The filet for the corner has been increased to prevent the stock wiper from hitting it. The orientation has been changed as well for strength which does not require supports. The open corner has been trimmed so it does not interfere with the build plate which occurred with the original on my P1S.

Requires a 5mm Brass Wire Brush with a 3mm (1/8") shaft. Example: https://www.amazon.com/dp/B0CR3ZBWTF

Be sure to insert the brush completely to avoid it being too high and possibly colliding with the nozzle.

I recommend printing in ASA or ABS.
