Handfree pull door handle adapter

Jeremy Pearce

Description

This works the same as for the pull adapter using the same inserts for different handle types. The main bracket is made from pla, petg etc. The adapter inserts are made from semi-flexible TPU, I use Ninja Cheetah. The inserts are designed to give a good grip as possible on the handle. The design requires M5 standard allen bolts and screws about 20 mm length. The bolt heads are recessed and the nuts captive. This makes installation quick and I hope reasonably tidy. If necessary it would be easy to make other adapters. They have been under test at work and the design is holding up fine. It helps to print in the brightest colours you can find so it is difficult to miss, and maybe look a little bright.

Materials and methods

For the bracket I use PETG at the moment I am using fillamentatums modified PETG (CPE). I use 0.4 nozzle with 3 perimeters and 3 layers top and bottom and 50% infill.

Both parts have a little support.
The seal adapters are printed in TPU with 3 perimeters, 3 top and bottom layers and 50% infill.
When installing only tighten the bolts sufficiently to secure the assembly, it is useful to recheck the security after some time and tighten the bolts further if necessary.
