Team UnLimited Thermo-form Reverse Dovetail Gauntlet

This release contains all the required files to create reverse dovetail thermo-formed gauntlets for e-nable devices and is currently compatible with both Raptor Reloaded and Phoenix hands. Printed in PLA the gauntlet is heated when printed to form a natural, strong gauntlet.

This release also includes the Autodesk Fusion 360 source archive to allow for easier modification and customisation of this gauntlet.

This development is based upon the initial thermo-form work by Andreas Bastian that is available here, from his R&D thread in the e-NABLE forum here.

This release contains the following files :-

  • V4 Thermo-form gauntlet, this scales at the same size as the e-nable device being produced.
  • Forming Jig to allow shaping to be performed without the recipient / without risk of burns to the recipient.
  • Several tension boxes :-
    • Team UnLimited 3 pin partial adaptive grip; more information on this can be found here.
    • Standard 5 pin tension box.
    • Gripper box for adaptive grip; more information on this can be found here.
  • Customised tension box pin that has an internal rounder surface for the Team UnLimited 3 pin adaptive grip system.

Team UnLimbited Thermo-form Reverse Dovetail Features

  • Reverse dovetail to allow for a more natural forming of the gauntlet without distorting the tensioner block interface.
  • Dual strap mounts to eliminate the use of wide velcro and the associated comfort problem it creates.
    • Use either narrow velcro double sided tape or pre-made velcro straps to secure the gauntlet; both available on eBay etc.
  • Crescent Moon front wrist pressure release area to aid with comfort.
  • Suggested lining material is Dr Scholl moleskin plus padding roll, if the device is correctly sized and formed then there should be no need for additional foam padding.
  • As ever the recipient should wear a prosthetic sock with any e-NABLE device.

Instructions

Print the Team UnLimited Thermo-form reverse dovetail gauntlet and Jig at the same scale size to the device you are creating; suggested print settings are :-

  • .2mm layer height
  • 35% infill (honeycomb if avalible)
  • 4 top layers
  • 4 bottom layers
  • 3 perimeters

We have put together the following video to show the method for forming the gauntlet we use, you could also use a hair dryer if you do not wish to use hot water. Please note that the thermo-forming process can be repeated multiple times to gain the desired shape.

SAFETY WARNING :- BOILING WATER IS HOT, IT CAN BURN, BE CAREFUL !
