Convertion kit for thompson m1a1 / Various Design

I have the permission of Foxstrat, author of the original model, to post this remix.

It is necessary to use the other parts of the original kit: https://www.thingiverse.com/thing:4019316

I present a variation of the design created by Foxstrat:

• Filling the holes of the original model to increase the strength and rigidity.
• Changed the decoration of the handguard to remind the original
• Added reinforcement pieces to the upper assembly areas that also allow the use of M3X8 screws.
• Removal of the central groove of the picatinny rails.
