2.2 RC Monster Truck Beadlock. 3 different offsets to fit a wide variety of models that use a standard 12mm hex. The truck pictured is an HPI Wheely King. These are specifically designed to fit JConcepts 2.2 tires, ie the Renegade Jr, Fling King Jr, and Midwest. They will probably fit Proline tires but you may need to trim the bead a bit for best fit. Hardware List per Wheel 6x M3 x 10mm (planetary cover) 6x M4 x 12mm (center hub) I printed these at 100% infill in PLA. Temps 215/60 to ensure maximum layer adhesion.
Update 2/15/21 I uploaded a new set of hex hubs with better clearances that should fit on the 12mm hex far easier.
Updated 8/12/21 New v2 design for more durability plus a new offset adapter.
