Rawnei Posted January 19, 2023 Author Share Posted January 19, 2023 (edited) Begode Master Bushing Stabilizers https://www.thingiverse.com/thing:5799376 The Master suspension has a lot of tolerance between the bushings and the pipe that they move on causing the suspension to feel "loose", Begode has added 4 small screws that you can adjust to tighten the bushings against the pipe but these are problematic for a couple of reasons: 1) It's difficult to adjust all 4 of these screw perfectly, if you tighten them to much it will cause friction and suspension will be noticeable more stiff 2) The screws push the bushing from one direction making it oval and also risk damaging them. These "stabilizers" is a ring that pushes the bushing from all directions and I've measured and tested them so that the bushings are as tight as they can be without adding friction. This was an original idea by Emanuele "@EMA" Tomasello who made a similar 3D design however I found that those did not work so well for me but I was intrigued by the idea so I measured my wheel and did a lot of tests, for one thing the upper and lower bushings need different sizes as the lower bushings are pushed in with countersunk screws while the upper ones are held in place by the suspension bridge giving them different tolerances, these stabilizers are also slightly bigger than the ones EMA made, the upper one is 2.5mm in height while the lower one is 1.5mm, both are 34.2mm in diameter and 0.75mm thick but gradually getting smaller from one end to the other.

Rawnei Posted February 17, 2023 Author Share Posted February 17, 2023 Update to Begode Master Seat Addon https://www.thingiverse.com/thing:5529643 Added a Version 2 of this seat that is a bit bigger and which has a little flatter shape on top, overall more comfortable.

Wow - have just got a quote from 3D people to print it, and they want a whopping £435 to do that !! I may have to think again ! 1 Quote Link to comment Share on other sites More sharing options...

Velcro yes, works great, there's images of the velcro attachment on the thingiverse link. £435 yikes that's extremely overpriced, for reference for me printing this it uses about 265g of material, 1kg spool of TPU 95A (somewhere between 750-800g of material on the spool) costs about £32 on amazon which would be enough material to print 2-3 of these (and then electricity cost of course but yeah..). Then it also comes down to understanding what you are printing, context matters for instance this is a seat and getting infill and texture right is important and someone who doesn't understand that might get it wrong and you will get a hard and slippery seat. Your best option might be to get a yoga block and shape it a bit. Edited February 17, 2023 by Rawnei Quote Link to comment Share on other sites More sharing options...

I see ! You don't wanna print me one for £100 do you ?! Lols - only joking, but at the sort of prices those guys want I might as well buy a 3D printer !! I'll start saving !

It's a great investment, so much stuff you can do, brought a lot of value to me personally! I have an Ender 3 S1 Pro printer, it costs around £470, not that much more expensive than the price they offered you for printing one item. 😅 Edited February 17, 2023 by Rawnei 1 1 Quote Link to comment Share on other sites More sharing options...
Cerbera Posted February 17, 2023 Share Posted February 17, 2023 (edited) Yeah, next time I have 500 quid spare I may well do that ! Still feeling quite poor after the Master though I can wait - I have earned my delayed gratification XP Gold star awaiting the wheel all that time, and seated riding can be a nice surprise for further down the road....

Popular Post Rawnei Posted March 15, 2023 Author Popular Post Share Posted March 15, 2023 Updated my waterproofing seal for the bearings: https://www.thingiverse.com/thing:5798147 2023-03-15: Complete redesign of this seal, it's smaller and more simple with the goal of not trapping any water and avoid rubbing against motor cover all together, this new version stops short before motor cover instead of extruding over it so that water can splash, drip and move past it. Due to this complete redesign it no longer support the "lazy" version installation, to install this seal you need to disconnect the motor cable. A waterproofing seal for the bearings on the Begode Master. The idea behind this seal is to add an extra barrier of protection outside the bearing with a layer of grease between them to further prevent water and dirt from reaching the bearing seal. 4 Quote Link to comment Share on other sites More sharing options...
EUCzero Posted March 19, 2023 Share Posted March 19, 2023 (edited) To protect your shock you need a better mud guard than original. The one from Ronnie is super, but its a big print. An alternative is this Mud guard holder that enables you to make the mudguard out of any piece of plastic sheet, PET bottle, yoga mat or similar. https://www.thingiverse.com/search?q=5919475&page=1&type=things&sort=relevant In instagram you can see the whole thing: https://www.instagram.com/p/Cp9ycdYAM4f/?hl=en Edited March 19, 2023 by EUCzero Quote Link to comment Share on other sites More sharing options...
Rawnei Posted April 7, 2023 Author Share Posted April 7, 2023 Update to my kickstand. https://www.thingiverse.com/thing:5505862 2023-04-07: Added a mudflap extension for my Master kickstand, I noticed that even with a very big mudguard on the Master there is enough space below the kickstand for the tire to splash water and dirt upwards towards yourself and on people behind you so I made this mudflap extension that adds onto my kickstand, you plug it into the lower mounting holes and screw it in place like you would the kickstand. Print in TPU and it will be soft enough to bend when you park the wheel on the kickstand or if the mudflap hits any obstacle it wont be a problem. 1 Quote Link to comment Share on other sites More sharing options...
EUCzero Posted June 19, 2023 Share Posted June 19, 2023 Slider sock (protection) Printing as we speak, so do not know how effective it will be in the long run. But my slider bushings are worn out. Should be 2mm thick. Down to 1.7mm worst place now. That is 0.3 + 0.3mm slack on the top and the same in the bottom. Really annoying while riding now. New bushings gonna be ordered, and this sock will hopefully protect them better. Print in TPU. Flat end mounted down.https://www.thingiverse.com/thing:6086503 Quote Link to comment Share on other sites More sharing options...
