Holder for 10 ER20 collets I designed. The units are stackable so you can hook two together.

I've also included the STEP and IPT file if you wish to modify the holder.

Print face down and with supports under the tabs.

Walls are 1.2mm so a 0.4mm nozzle prints it perfectly with the only infill being on the face.

Just remove the supports from under the tabs. Flip it over and drop your collets in.
