Keen-One Counterweight adapter

prusaprinters

<p>This is an adapter to hold a M12 Hex Extension Coupling Nut. The nut goes inside the adapter, and then the adapter bolts directly onto the declination axis. This should fit most common M12 counter weight bars, allowing the KEEN-ONE to handle larger payloads. I've tested this up to 17 lbs. An extension nut was used to provide more surface area for the counterweight to press against. You could try using a regular M12 hex nut.&nbsp;</p><p>Items Needed:</p><p>1 x M12 Extension Coupling Nut</p><p>4 x M4 x 20 screws</p>
