TRS-80 Model I – Screw Standoffs Plate

Creator: Barrakuda

Last Update: July 18, 2018

Official Link: https://www.thingiverse.com/thing:3010034

Summary:TRS-80 model I computers have screw standoffs that can break or get stripped over time. This screw standoffs plate can be used to replace all screw standoffs completely.

The standoffs plate needs to be printed in two separate pieces due to the length. Unit of measure is millimeters (mm).

To install, remove all original screw standoffs with a rotary tool like a Dremel. Then, use a strong epoxy plastic adhesive to glue the plate down to the surface plane where the original standoffs used to be. Make sure the plate is positioned so that the new screw standoffs align with where the original standoffs used to be.

NOTE: Before permanently gluing this to the case, do a test fit with a hot glue gun.

TRS-80 Model I – Expansion Interface Port Cover

Creator: MrLurch

Summary: This is a replacement cover for the Expansion Interface port on the Radio Shack TRS-80 Model I computer. It’s been modeled by taking precise measurements of an original cover. It fits really well, but you might have to shave off a little bit from one of the sides if it does not fit correctly because the opening on the TRS-80 seems to be a bit angled. Just use a razor blade or even fine sand paper.

Print it standing up, with the hooks pointing up. Use supports.

The Mod I unit port cover is an edit of “TRS-80 Model 1 – Expansion Interface Port Cover by barrakuda

Blank Cover Printing:

When printing, it’s probably simplest to position the blank covers face down on the print bed. I’m going to experiment printing them upright to get a smooth external surface, but I could possibly more effectively solve the surface problem by using epoxy and paint.

Connector Hood Cover Printing:

The nicest prints of the hooded covers are produced when you stand them up with the connector bracket toward the top of the model. You’ll need to enable supports, but probably only on the “inside”.

Use double sided tape between hood covers and edge connectors to hold cover on. They don’t fit tightly enough to stay in place otherwise.

Hot-glue a small metal washer on the underside of the keyboard to use with this support.
