Reddit reviews Teenitor Silicone Thermal Pad for CPU GPU Heatsink and Hold The Glass Plate On Heated Print Bed for 3D Printing 400mm x 200mm x 0.5mm

Use a silicone mat it will hold the glass in place without clips plus transfers the heat more evenly and efficiently.

What you absolutely MUSTTTTTTT!!!! order? Nothing. The printer works as is. But if you want to do yourself a favour, here's a list of what I consider essentials:


- New springs, both bed and extruder. I don't have a link for an extruder one as I upgraded my entire extruder drive frame and that came with a better spring

- A new removable bed. Creality glass bed or glass with a PEI sheet is my bed of choice

- Thermal pad to avoid the annoying bed clamps. Cut squares out of it, lay them in a checkered pattern alternating between thermal pad and nothing and place your bed on top. They will hold the bed in place and help with heating

- Stepper dampers if your printer is anywhere near where you spend your time, it sounds like a bloody jackhammer right out of the box

- New tube fittings, the stock ones are terrible and will give out in a matter of weeks at best. They also barely hold onto the tube

There are a ton of other great upgrades, but I think a good idea is to get a feel for it yourself.

What you can do, however, is check out some printable upgrades. I have this thread where people contributed with their choice of printable upgrades. It's a great list you can refer to later. Essentials on that are the fan guard and LCD back cover simply because the Ender 3 as is has the fan and back of the LCD exposed and that makes it crazy vulnerable to dust and gook damage

That is the one that I ordered. Some people have said that they would rather use a 5" diameter disc, but 4-1/2" is a near perfect fit over the existing build surface. I removed the build surface (while the bed is heated to 60°). Then cutout a piece of silicon thermal pad the sane size as the glass and sandwiched it between the plate and glass. Works well and holds it pretty firmly. https://www.amazon.com/gp/product/B06XX7ZMN7/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

and it has worked great. I cut it in half and let a friend use the otehr half. NO MORE BINDER CLIPS! I freaking hated those clips from day 1.

I would get a glass bed, a thermal mat to adhere it to the heated bed, buy longer screws and some washers (for keeping the springs compressed)

Once it is up and running, you can swap the washers for some printed spacers.

No I have a thermal silicone sheet between the glass and the heat bed. Serves 2 purposes. Conducts heat to the glass and kinda grabs the glass and holds it in place.
