This is a TPU version of my first model to replace a suitcase wheel.

Features

• The structural parts can be printed in any hard and durable material (I use PETG)
• The part that has contact with the surface can be printed in TPU or any other flexible filament that will work for this setup

Construction

• You need the “upper” and the “lower” part printed in hard and durable material
• You need to print the “ring” part in TPU or Flex
• The “ring” part goes in the middle and the two “upper” and “lower” parts will hold it in place

Printing

• Hard parts: 
  • Use a minimum of 4 (better 6) perimeters. I printed it with a 0.6mm nozzle (3.6mm). 
  • The more perimeters you have, the stronger the holder will be. This two parts are structural parts and need to be strong
  • Use support from build plate only
  • 
• Soft Part
  • I used 3D Jake TPU with a shore hardened of A95. It is very hard, but still minimal flexible.
  • Depending on your material: I had to split the ring in the middle and print the half with the big flat part facing the print bed. I just printed 2x the half's. With this TPU I had problems on the overhang so I couldn't print it in one size. 
  • 
  • No support
  • Brim is highly recommended. I had inner and outer brim (1cm each) to make sure the parts where holding on my printbed)

BOM

• 6x M3 screws (16mm lenght)
• 6x M3 nuts
• 2x “oben” (hard part)
• 2x “unten” (hard part)
• V1: 2x ring_full (if your TPU can handle the overhangs)
• V2: 4x ring_half (with this you should be able to print any flexible filament, no overhang no support)

Assembly guide

• Step 1
  • V1
    • Put the TPU ring over one of the parts
    • Stick the two hard parts together
  • V2
    • Put the two half parts of the ring over each of the hard parts. Make sure the flat side of the parts are inwards
  • 
  • 
  • 
• Step 2
  • Use the screws and the nuts so the wheel will hold together
  • If you hear a “noise” when you shake it: The screw is to loose, you need to tighten it more
  • Yes, you need to tighten it really hard, this is why I used PETG
  • The wholes are just a bit to small, you have to push (when screwing) the scrubs in. This is on purpose to make it more stable.
  • 
  • 
• Step 3
  • Replace the wheels
• Step 4
  • Upload a make ;)
