Oil Heater wheels

The wheels of my heater were broken and I decided to design some new and oversized wheels for it. You should print in PETG/ABS/ASA to withstand the temperature. The hole has 2 measures inside, 6.40mm and 6.70mm, so it will click and hold when you install the support on the heater. Please resist the temptation to install the wheel in the body prior to the body into the heater. You will need quite force to install the body on the heater (I need to put some pressure with my foot), and if you already have installed the wheels you could risk to break the fittings.
