Z42 Prusa Mini/ Mini Plus Wide Side Spool Holder

Reupload because I deleted it by mistake.

For my application the stock spool holder for the mini didn't work out well. So here we have a side spool holder that I designed to reduce the Mini's overall footprint and make changing filament easy and convenient. It mounts to the Y axis 3030 extrusion and sits on the desk/workbench surface. This is the wide version that makes the printer  a bit wider but allows for those of us with big paws to access the control screen easily.

You can get the narrow version here: Z42 Prusa Mini/ Mini Plus Narrow Side Spool Holder

You will need
3 M4x12 bolts (for the extrusion mounting and the rod)
2 M4 3030 extrusion T nuts

To attach the rod you can use up to a M4x20, if necessary.

This version is for Prusa Mini or Mini Plus, it is adjustable to fit either model at a stock or similar to stock height.  I have another version with a foot that can be printed to fit various styles of Prusa Mini heights due modifications.

Print instructions

The model in the photo is printed in PLA at .2 layer height, variable layer height enabled with 3 clicks of smoothing, 3 perimeters and 25% infill.

To make this easy you can use the 3mf file or the Gcode for the mini or MK3

If you use the 3mf be sure to adjust for your filament.

The gcode file is for Prusament PLA.

For assembly 1 M4 screw goes into the hole at the top and screws into the spool holding rod.

2 M4x12 screws go through the 2 slots at the bottom of the arm, place t-nuts on them with the flat sides facing the model. Then slide the t-nuts into the slot in the 3030 extrusion at the location shown in the picture. Tighten the M4 screws to snug while holding the arm against the work surface. Once the screws are snug give the arm a slight pull away from the 3030 extrusion to ensure that the t-nuts caught in place. If the arm doesn't move then you are golden, if it does, you'll need to loosen up the M4 screw for the offending t-nut and try again.
