All of the m10q mount designs I've tried contain incorrect geometry that places heavy loads on delicate SMD components found near the edges of the GPS pcb. These designs actually have to be printed with TPU otherwise they will damage the GPS during assembly! I like TPU, but I wanted a more optimized design that doesn't touch delicate SMD parts. So I drew some stuff up in fusion, did some test print and tweak iterations, and ended up with this thing which is much safer to use, even if it's printed in PETG (pla too, but don't use that on near any heat).

The mount does not touch any delicate SMD components during assembly, disassembly, or operation. It locks the GPS down securely using only PCB material and the connector housings for support (the connectors are designed to be robust vs capacitors etc). There is an optional snap on cover to further protect the antenna and wires entering the connector. The cover is not necessary as the base is designed to be very secure on it's own. The STLs include a basic compact mount that can be attached with double sided tape. There is also 2 other pole style mounts; A and B. Both have hole on the base to fit M3 hardware, and a small "key" under the base to stop rotation when mounted using a slotted hole. This key is rotated 90* between A and B to allow for use with longitudinal or lateral slots. If you are using a round hole, cut the key off with flush cutters or similar. In this case 2-sided tape can be used to stop rotation. This is important since the m10q has a compass built in.

Printing... nothing special, no rotation, no supports, heck not even tpu is a requirement. I printed mine in PETG 0.3mm layers and they work perfectly. You can use ABS, TPU, or whatever you like.

Assembly manual: slide until it clicks into place. Same with the cover if you are using one. Make sure your wires are out of the way while installing the cover.

Cheers, and enjoy the hobbies!
