This original 1/10 scale filler cap comes in 4 versions. Large and small, with both being threaded and non threaded.

All versions are a 1 piece print. The large version comes in M4 threaded and 4mm stub. The small version comes in M3 threaded and 3mm stub.

The M3 and M4 threaded versions are designed to accept an M3 and M4 nut directly, respectively to secure the filler cap. These threads are designed extremely accurately, and therefore have very tight tolerances. Tested on our resin printer, even with a 0.04mm layer height will print the threads accurate enough for a standard M3 and M4 nut to fit without any issues. 

You may have to very slightly rescale the print file in your slicer if the printer is not accurate enough. Resin printed products tend to be larger than the designed dimensions, on a small scale so size compensation might be needed. If the nut does not fit nicely onto the threaded shaft, then it is possible to use a tap and die kit and thread the printed threads to clear enough space for the nut.

However the non threaded version exists should the threaded version just can’t be made to fit with your setup. The 3mm and 4mm diameter stub version does exist in large and small versions, which can be threaded in M3 and M4 respectively.

 

Same with all of our other print files, it is highly recommended to print only with a resin printer to achieve the maximum amount of details, and do remember to wear PPE.

Post processing is the same with our other products. Use a spray primer depending on your resin type, then either spray paint or hand paint with model paints to your own liking. Top it off with thin coats of UV-proof clear spray. Feel free to use the renderings as an inspiration for your colour schemes!
