About this 3D model

**** Check new model - https://makerworld.com/en/models/183750#profileId-202603 **** I couldn't find anything that works with https://makerworld.com/en/models/63021#profileId-65721 so I designed this. Please note: It is not made too tight, as first versions I was testing would pop out the front cover on hard stops or fast changes of direction.
