2kg Spool Holder Extender for Prusa Enclosure

This model extends the injection molded part that comes with the Prusa Mk3 family of printers so that it can hold 2kg spools and remain compatible with the Prusa Enclosure.

Printing

Orientation

I recommend printing this vertically (as oriented in the file) since it doesn't need supports in this orientation. 

Bed Adhesion

It should be fine to print without a brim, but if you want to be safe you could add one.

Infill

Infill percentage and style don't matter because there is very little of it.

Layer Height

A smaller layer height might yield crisper details, but I had minimal sagging of overhangs and a nice fit at 0.3mm layer height with no supports.

Material

PLA and any other material with some rigidity and strength should be sufficient. I used Prusament Recycled PLA and had great results. It is plenty strong.

Design story

I remixed @MartinL_254131's model because it was not structurally sound and crumpled in my hand when I printed it, but I really liked the design. I also wanted a more secure interface between the parts than press fit. I utilized the locking mechanism on the injected molded part that comes with the enclosure and put it inside of MartinL's design. I also thickened the outer wall and removed the exterior pattern which is what made the print weak in my experience. I like that it can be easily removed to not take up extra space if you typically print with the 1kg spools. I hope you enjoy it as much as I do!
