feet/shoes for a folding ladder 40x20mm

The other day I bought an aluminum ladder from a reputable manufacturer as part of a special offer. The ladder was perfectly fine, however, the feet were completely unsuitable for use in the apartment (they had rude PP plastic shoes with integrated wheels).
When I then looked for new shoes made of rubber, I was very surprised that they were outrageously expensive. Depending on the design between 20 and 50 EUR, plus shipping.

You can make them yourself much cheaper!

• The present design is for folding ladders with stiles with outer dimensions 40x20mm and 70° stand angle
• The sole of the shoe is broader for a safe stand, namely 62x42mm
• To ensure that the folding ladder stands straight, all 4 shoes must be replaced
• The shoe should be printed in PETG for safety reasons
• The adhesion to the ground is achieved by glued rubber mats
• A cutting template for the rubber feet is included with the files
• The shoes also have a countersunk hole if you want to screw them to the ladder
