Bear Instant Water Heater Riser Base

For the instant water heater used in road trips, most cups do not fit due to height constraints, so I made a base I am a novice at 3D modeling and simply created this using Makerlab There is a wire connector at the back of the hot water dispenser, for which I manually cut an opening with a utility knife, measuring 2x1.5 cm Perhaps someone more skilled could help create a proper cutout The overall external dimensions of the base are 112x112x135 mm, with an internal circular diameter of 110 mm I printed it with ABS, using approximately 300g of filament While the infill could be reduced, I believe this amount makes it more stable, which is important since it will be in a car, minimizing the chance of deformation Thank you for any feedback The size in the initial pictures was slightly too small, so I made adjustments, and now it fits perfectly and is very sturdy After learning some basic modeling for a few days, I created a second version of the raised base The lower part of the base was designed as a box to store components such as the pump tube and converter cap The upper part of the base and the lower part's lid were integrated This design uses less filament overall and makes more efficient use of space
