Rather than provide endorsement for a list of 'recommended mods', it would be more appropriate to approach this topic by instead providing a snapshot of the mods fitted to a user's printer. While each individual user may be satisfied with their own choices, one can't guarantee that you will have the same experience. YMMV. No liability for voided warranties etc.
