XRP Tiny Frame (DWG/STEP)

Supportless miniature version of the holey XRP frame. Uses half the filament (67g vs 132g for ABS).

The batteries are mounted above the wheels for more traction and the only part that sticks above where the wheels go is the power cord. This model has higher clearance than the original!

The motors snap into place just like in the original and I highly recommend pulling the motor wires through the center before adding the PCB for ease of routing.

The PCB snaps into the rear bracket. DWG/STEP files included so that you can tweak it if your printer doesn't get that perfect fit.

The battery pack has two different mounting options.
If not using the servo motor, there is a front bracket that goes into the hole between the 2nd and 3rd battery which keeps everything in place. Once again, DWG/STEP files included if you don't have a perfect fit.

If using the servo motor, there are two different new versions of the servo motor bracket. The one named “battery holder - slit” is my personal favorite. I recommend attaching the bracket before adding the batteries and sliding it all the way to the side, then adding the battery pack.
After adding the battery pack you will need to wiggle it into place until the plastic divider between the first and second battery goes into the slit. Your batteries will never move again and the servo motor arm is centered on the robot.

The other version of the servo motor doesn't have a slit and simply slides into place without wiggling. This does allow for sideways play of the battery pack, unless combined with the front bracket.

Once again, DWG/STEP files included in case your printer has different tolerances from mine.

If you decide to use the servo motor, I would recommend downloading and printing the straight version of the Lifter Hook from https://www.printables.com/model/966234-alternative-xrp-lifter-hooks

I printed mine in ABS but PLA or PETG might be easier to print in.

The parts in blue are PETG parts printed from the original XRP design and fit perfectly on this model.

I made the frame 80mm narrower and 60mm shorter. This prints without supports and uses half the filament.
