Description

PDF

I've designed a replacement bumpon for the Norbauer Heavy Grail mechanical keyboard, designed to be a friction-fit, removable solution. Intended to be printed in flexible filament, such as TPU.

Print settings

Stock 0.40mm diameter nozzle with 0.2mm is recommended.

The units on this listing were printed on a Voron V0S1 (LDO kit) with Varioshore TPU filament. 0.4mm diameter nozzle @ 0.2mm layer height. 

Kindly note, the feet are designed for a snug friction fit. Tune your slicer’s X and Y scale in small increments to dial in the perfect fit before printing a full set.
