Knobs with pointer for RC transmitter (JR8103)

Update Nov 2020: I made a simple knob that fits Spektrum and Taranis radio as well. The files are Tx-Knob-2. The Tx-Knob-2_adj has its scaling settings tweaked in Prusa slicer by just a hair to make a better fit.

Two knob models which go over the pots on my JR 8103 radio control transmitter. They help you know the radial location of the pot/dial on the TX while flying.

Instructions

The inner diameter is made exactly so you can force it down on the knob. You may need to increase the inner diameter on the bottom with a sharp knife. It needs to be built without a raft.

Knob1: simple thick outer dia

Knob2: has beam on top, and also flattened sides for extra 'feel' while flying, model has a top beam which sags a bit due to the air bridge.
