TRBboy Posted December 31, 2023 Share Posted December 31, 2023 Hey folks! I'm about to start turning an old TE combo into a compact 1x15" cab, but I'm struggling to find any port rings that'll fit.... I have one of the originals, but it's a bit tatty, the other is missing altogether. I don't seem to be able to find anything similar in the right size, does anyone have any suggestions? Thanks 🙏 Quote Link to comment Share on other sites More sharing options...
SamIAm Posted December 31, 2023 Share Posted December 31, 2023 (edited) Looks like a job for 3D printing! 🦸 In fact, this chap has uploaded a design for something similar. https://www.thingiverse.com/thing:4406135 I'm in the process of trying to get my 3D printer up and running again and would be able at that point to help out. @rwillett might be able to help also. What are its dimensions in mm? This will help determine if it is of a suitable size for the printer I've got.

rwillett Posted December 31, 2023 Share Posted December 31, 2023 Hi The maximum external diameter I can print in one piece is 220mm. However if it can be broken down into smaller pieces, that allows it to be bigger as it's then glued. All depends on the external diameter 2 Quote Link to comment Share on other sites More sharing options...
rwillett Posted December 31, 2023 Share Posted December 31, 2023 Looks fairly easy to print though. 2 Quote Link to comment Share on other sites More sharing options...

rwillett Posted December 31, 2023 Share Posted December 31, 2023 I can't print anything til end of next week though as I'm away. 4" is not a problem though. 2 Quote Link to comment Share on other sites More sharing options...

If it is the same as the thingiverse design, then it is printable on a Prusa (which is the device I've got). Sam x 1 Quote Link to comment Share on other sites More sharing options...
fleabag Posted January 1 Share Posted January 1 (edited) Buy one of these for £6.31 posted and cut the tube off, and leave an inch of tube so some of it will poke inside the cab, and run a bead of silicone round it to keep it in place. https://www.ebay.co.uk/itm/133538144762?chn=ps&_ul=GB&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&mkscid=101&itemid=133538144762&targetid=1404115578853&device=c&mktype=pla&googleloc=9046134&poi&campaignid=17218284410&mkgroupid=142217514411&rlsatarget=pla-1404115578853&abcId=9300867&merchantid=7255684 My mistake - £6.51 Edited January 1 by fleabag 2 Quote Link to comment Share on other sites More sharing options...
TRBboy Posted January 1 Author Share Posted January 1 Wow, thanks for the help guys! By my rough measurements, the OD of the port tube measures around 108mm. What would be the cost to get something like this printed? 1 Quote Link to comment Share on other sites More sharing options...

What are its dimensions in mm? This will help determine if it is of a suitable size for the printer I've got. Sam x Your sketch is a good start but a little bit too basic. It appears identical to my 1518 port grill interface jobbies. The tube comes through the baffle from inside the cab. Last I measured it had a 4" internal diameter but OP can confirm. The inside is less important than the outside measure of the tube. The ring trim adds just a little to the port as it mostly sits around the port tube to provide a clean look to the grill. It needs to finish the last 1/8" of collar with the same ID as the tube and the remaining ID of the collar that is doing the grabbing of the tube has to be the same as the OD of the tube, or ever so slightly less for fitting and glueing. 2 Quote Link to comment Share on other sites More sharing options...
rwillett Posted January 1 Share Posted January 1 Can you draw with sizes the above? It doesn't need to be an accurate drawing, but the measurements need to be accurate. Preferably in metric. If the ID is 100mm, then state that, the drawing doesn't need to be 100mm itself. Which part is the collar? Are the edges at 90 degrees or are they chamfered or rounded? How much does the internal tube stick out? Is the port two pieces or one? I'm in Spain for a few days and thingiverse isn't working for me Are there any mounting holes? If so what's the diameter of the holes? What's the spacing angle between the holes? The design looks easy to print but the devil appears to be in the details. I suspect once every measurement is known, it'll be a few mins work in F360. But we need every measurement and if edges need to be chamfered or whatever. If its going to be printed, make it exactly what you want. You can work to 0.2mm or less if you need to Rob 2 Quote Link to comment Share on other sites More sharing options...
TRBboy Posted January 1 Author Share Posted January 1 Thanks for all the help guys, @SamIAmhas kindly offered to help me out, so I'll be posting the only existing ring to her to scan in. I've not been on BC for a while, but this has reminded me why this forum is the best! 😊🙏 3 Quote Link to comment Share on other sites More sharing options...
rwillett Posted January 1 Share Posted January 1 Great. Let me know of you need any help. Rob 2 Quote Link to comment Share on other sites More sharing options...
BassmanPaul Posted January 1 Share Posted January 1 Why not just try Peavey in the States? They own the Trace brand now. Perhaps they have the proper port for your cab. 1 Quote Link to comment Share on other sites More sharing options...

I've looked at British Audio Service, who have loads of NOS spares for Trace gear, but it looks as though the port trims haven't been available for years now unfortunately.

BassmanPaul Posted January 1 Share Posted January 1 So try Peavey. At worst they can only say that the trim rings are not available. 1 Quote Link to comment Share on other sites More sharing options...
Downunderwonder Posted January 2 Share Posted January 2 Afaik Peavey only support the stuff they made, if that. 1 Quote Link to comment Share on other sites More sharing options...
BassmanPaul Posted January 2 Share Posted January 2 Fair enough. I did try a quick search on their site but came up empty. Quote Link to comment Share on other sites More sharing options...
