Shoe Dryer for Towel Rail Heater

I needed to solve the problem of how to effectively dry (especially children's) shoes on a towel rail heater. This solution works perfectly for me and can hold practically any shoes, not only children`s. 

Designed for 20 mm rail diameter with 20 mm gap between the rails. I will be happy to adjust for any other dimensions, if needed. 

Print with heat-resistant filament! I recommend ASA (the print in the photo uses Prusament ASA Prusa Galaxy Black).

I have printed mine with exposed infill: top and bottom solid layers set to zero, 6 perimeters, Triangles infill pattern with 40% density. However, this is more of an aesthetic matter and you can use different settings if you like.
