The Acorn by Slestak75

The Acorn! The one true organic. 

Comes in two flavors, fixed axle and unresponsive c bearing. 

For the fixed axle you will need

• 2x printed halves

• 1x 4 mm x 20 mm stainless steel pin 

• 2x mr85 response pads (or flowable silicone)

• super glue

Print them out, use supports for the cup, add the response pads, rough sand the end of the axles, drop of super glue in the holes, glue it all together and wait a day. 

For the unresponsive you need

• 2x m3ns square nuts 

• 1x m3 x 18 mm grub screw

• 1x unresponsive c bearing

• 2x slim 19 response pads

You will need to pause the print at ~18 mm height using a color swap or pause command in your slicer and then drop the nut into the recess and resume printing. Then once done install the pads, axle, bearing, and you are good to go.
